The East Asian Himalayas are its primary habitat. Overexploitation and overharvesting pose a threat to this plant, given its extensive ethnomedical utilization in the community. In Pakistan, its population has already declined by over 75%. Given its critical medicinal importance, urgent conservation efforts are needed to prevent extinction. The aim of the current research was to determine the effectiveness of sucrose and polyethylene glycol (PEG) in decelerating the growth of this medicinally important species. Nodal segments were utilized as explant with varying levels of polyethylene glycol (PEG) (0.5% and 1.5%) and sucrose (4% and 8%) as treatments on different growth attributes. Over a 45-day period, PEG treatments (0.5% and 1.5%) proved more efficient compared to sucrose in suppressing in vitro growth, with reduced shoot lengths (0.92 and 0.57 cm), dry weight (0.04 and 0.02 g), and fresh weight (0.06 and 0.04 g). PEG also significantly enhanced phenolic levels (0.96 and 0.19 mg/g) and soluble sugars (4.07 and 4.12 mg/g) while reducing total protein level (2.38 and 2.32 mg/g) and total chlorophyll content (0.17 and 0.14 mg/g). The Pearson correlation analysis showed a negative association between phenolic levels and total chlorophyll content, chlorophyll a, and chlorophyll b. The length of the shoot had a negative relationship with phenolic level but a positive relationship with both fresh and dry weight. The principal component analysis revealed that total sugars and phenolics that were grouped separately from other variables led to stronger responses to osmotic stress. These outcomes suggested that higher PEG was successful in reducing in vitro growth throughout short-term preservation in comparison to sucrose. The outcomes of this research could be applied for the in vitro conservation of medical plants in the future.展开更多

PCR-SSCP was used to analyze the polymorphism of leptin gene in 539 samples of six cattle breeds, namely Nanyang （NY）, Qinchuan （QC）, Jiaxianred （JXR）, Xizhen （XZ）, Luxi （LX）, and Holstein cow （HOL） breeds...PCR-SSCP was used to analyze the polymorphism of leptin gene in 539 samples of six cattle breeds, namely Nanyang （NY）, Qinchuan （QC）, Jiaxianred （JXR）, Xizhen （XZ）, Luxi （LX）, and Holstein cow （HOL） breeds. PCR products with a 330 bp were amplified and sequenced. The results showed that the frequencies of alleles A/B of NY, QC, JXR, XZ, LX, and HOL breeds were 0.558/0.442, 0.492/0.508, 0.571/0.429, 0.658/0.342, 0.591/0.409, and 0.615/0.385, respectively. The association of variations of leptin gene with growth traits in NY, QC, JXR breeds was analyzed. Some indexes of the individuals with genotype BB were higher than that with genotype AA and AB in NY breed, such as the indexes of body length, heart length, body weight, hucklebone width, body height, and average day gain. The height at hip cross of the individuals with genotype BB was higher than that of those with genotype AA and AB in QC breed （P 〈 0.05）. So leptin gene may be one of the candidate genes for growth traits with height at hip cross, but not for body weight, heart length, and body length trait. However, the height at hip cross and hucklebone width of the individuals with genotype AB and BB were higher than that of those with genotype AA in JXR breed （P 〈 0.05）, but the difference was not statistically significant in body weight and body sizes （body height, body length, and heart length）. And the polymorphisms in leptin gene were caused by G→T transversion at the 66th bp position, A→C transversion at the 67th bp position and G→T transversion at the 299th bp position. These results may be applied to marker-assisted selection of Chinese cattle breeds.展开更多

As a result of pollution and invasion of exotic fishes, the fish had disappeared from Dianchi Lake since 1986 and only a few small populations survive in springs and streams around the lake. Due to the endangered status and special scientific value, S.grahami was listed as the second class protective animal of China in 1989. The importance of S. grahami and the indigenous biodiversity of Dianchi Lake were recognized by the Global Environment Foundation （GEF） /World Bank and Yunnan Development ＆ Reform Committee. Therefore a special grant was set up to restore and conserve the indigenous biodiversity of Dianchi Lake. The artificial breeding of S. grahami is a part of the targeted activities. Two successful breeding experiments were achieved using five females plus six males up to early March 2007. Approximately 1600 eggs were collected, of which 1320 eggs fertilized using the dry-fertilizing method. The mean fertilization rate was 73%. Approximately 480 fish fry was hatched and the mean hatching rate was 36%. After 10 days of cultivation, 95% fingerlings survived and their body lengths were up to 8- 12 mm. The importance of the artificial breeding success of S. grahami could be summarized as following： effectively protecting the fish from extinction; releasing the fish fry back to appropriate water body of the lake could help to restore the indigenous biodiversity of Dianchi Lake; facilitating the shift of local fish cultivation from the present non-indigenous to the future indigenous fishery.展开更多

文摘Indigenous microbial communities were employed after subculture in stirred and column bioleaching experiments involving ion-adsorption type rare earth ore.The microbial eukaryotic communities exhibited dramatically varying diversity and structure across culture compositions.Compared with Czapek and sucrose medium,the community cultured in a nutrient broth(NB)medium had a high-er diversity,and it was mainly composed of Zygosaccharomyces,Ustilago,Kodamaea,Malassezia,and Aspergillus.These microorgan-isms secrete organic acids,such as citric acid,malic acid,gluconic acid,and itaconic acid,which provide effective coordination electrons through hydroxyl and carboxyl groups.Stirred bioleaching experiments were conducted to investigate the effect of community,inoculum dosage,liquid–solid ratio,and time on the leaching efficiency.Stirred bioleaching resulted in a concentration limitation phenomenon.When the inoculum dosage of the community cultured in NB medium was 70vol%,the liquid–solid ratio was 5.0 mL·g^(-1),and the time was 60 min,the upward trend of rare earths leaching rate has become very small.Specifically,the leaching rates of detectable La,Ce,and Y were approximately 92.49%,92.42%,and 94.39%,respectively.The leaching efficiency and the three influencing factors all con-formed to the Poly5 polynomial function,with variances above 0.99.Column bioleaching experiments were performed at a scale of 1 kg.The self-propelled low-pH environment increased the leaching efficiency,which resulted in a leaching rate of 98.88%for rare earths after 117 h.X-ray diffraction and scanning electron microscopy revealed that the samples mainly comprised quartz,kaolinite,orthoclase,mus-covite,and zeolite,which were predominantly present in the form of lumps,flakes,rods,and small particles.After bioleaching,the wave intensity of quartz,kaolinite,orthoclase,and muscovite increased,and that of zeolite decreased considerably.A diminution in the number of fine particles indicated the dissolution of small quantities of clay minerals.Ultimately,the differentiated bioleaching mechanism of various forms of rare earths was discussed based on experimental phenomena.
文摘Studying the interactions and relationships between humans and animals is known as ethnozoology.Indigenous medicine that is used to prevent,diagnose,and cure physical and mental disorders is known as traditional medicine.The understanding of how various animal materials are used in conventional medicine by different ethnic communities is undocumented and largely passed through oral communication from generation to generation.Traditional medicine is the primary source of healthcare for many ethnic tribes in Ethiopia.Approximately 80%of Ethiopians rely on traditional medicine to cure a variety of human conditions.However,because they are passed down orally from generation to generation,this indigenous medical practice is being disregarded and is still disappearing as a result of inadequate documentation.Ethiopia is a land of diversity,with a wide variety of fauna and ethnic groups,each of whom uses and manipulates medicinal animals in a unique way to treat a range of human illnesses.The main participants in the curative component of traditional medicine practice are traditional healers,who go by various names in different regions of the nation.In Ethiopia,though indigenous societies medicinally used animal species for millennia,they have given little attention to their conservation.Therefore,documentation of traditional medicinal animals and indigenous healing practices of Ethiopian cultures are very important to preserve the country’s resources.
文摘Indigenous cultures prescribed a means of maximizing the benefits they produced and enjoyed in their relationship with each other and the environment-based on their understanding of the nature of existence and how to live in harmony with the forces shaping the nature of existence.The emergence of civilization introduced the claim that rational abilities superseded indigenous knowledge.This was followed by positivism and the claim that knowledge passed through three stages:mythological,philosophical,and scientific.This impacted indigenous cultures in ways that reached a height when postcolonial development experts convinced national leaders that progress required adopting advances in science.A failure to modernize was regarded as holding back progress.With the development paradigm now regarded as inadequate for achieving its goals and with the rise of the sustainability discourse,there is appreciation for indigenous knowledge.This article describes an indigenous cultural knowledge system that reflects the insight and wisdom of the world’s most respected scientific and philosophical traditions.The beliefs of the Bodo people of Northeast India are used as an example of an indigenous worldview that portrays insight proven to have value that is comparable to the natural sciences,plus theories of natural law and political philosophy.

文摘Prominent cadmium(Cd)pollution and widespread phoxim(p H)use hinder the growth and medicinal value of Ligusticum chuanxiong Hort.(Chuanxiong).While bioremediation by rhizobacteria helps plants counter pollutants,the specific roles of indigenous resistant consortia collected from polluted soils in immobilizing heavy metals,degrading pesticides,and enhancing plant stress tolerance remain insufficiently explored.Here,an indigenous pollutant-resistant consortium(RM)was developed from a highly Cd-polluted area(14.85 mg/kg Cd)as a bioremediation strategy to alleviate stress on Chuanxiong.The RM was specifically enriched with a Cd-p H co-resistant strain,Halomonas spp.TS2.Through16S r RNA sequencing,active microorganisms within RM was identified,including Bacillus,Acinetobacter,Enterococcus,Paraclostridium,and Staphylococcus.Pot experiments demonstrated that RM increased Chuanxiong biomass by 93.38%under Cd-contaminated and by 32.89%under Cd-p H co-contaminated.Furthermore,RM enhanced p H degradation,stabilized soil compounds,and reduced Cd bioavailability,thereby mitigating oxidative damage and altering the diversity and composition of Cd-p H-resistant organisms.These results indicate that utilizing indigenous microbial consortia as a bioremediation strategy can effectively improve soil health and enhance the sustainable cultivation of medicinal herbs in environments heavily contaminated.

文摘The Māori people are indigenous to Aotearoa New Zealand,and their language and culture are considered vital components of the nation’s cultural heritage.However,Te Reo Māori is regarded as a lowresource language outside of New Zealand,and its literary works usually rely on English as a pivot language for translation and communication.Therefore,in the process of promoting Māori literature as part of world literature by translating it into non-English languages,the accurate translation of cultural keywords is crucial to prevent dilemmas such as information loss and cultural misappropriation.In this article,we aim to explore effective translation strategies to enhance the international visibility and readership of Māori literature by analysing the rendition of Māori cultural keywords in the Chinese translation of“The Whale Rider”.
文摘Multifocal epithelial hyperplasia(MEH),also known as Heck’s disease,is a rare and benign condition of the oral mucosa that is strongly associated with low-risk human papillomavirus(HPV)genotypes 13 and 32.This narrative review synthesizes recent findings regarding the epidemiology,viral mechanisms,clinical and histopathological features,diagnostic strategies-including molecular and immunohistochemical methods-and therapeutic approaches to MEH.This disease predominantly affects children and adolescents from Indigenous American countries,although cases have been increasingly reported in nonendemic regions.MEH manifests clinically as multiple,asymptomatic papules or nodules,typically exhibiting a characteristic cobblestone-like appearance.Histologically,it presents with epithelial hyperplasia,koilocytosis,and altered cytokeratin expression.Molecular techniques such as polymerase chain reaction and in situ hybridization are pivotal for accurate viral genotyping,while immunohistochemical markers such as CK4/13,Ki-67,and the absence of p16 can be useful adjuncts in differential diagnosis.Despite its self-limiting nature in most cases,treatment may be warranted in symptomatic or immunocompromised patients.This review highlights the need to improve diagnostic access,develop targeted vaccines,and implement public health strategies in vulnerable communities.It also highlights existing gaps in knowledge,particularly regarding host-virus interactions and the absence of standardized treatment protocols.

文摘The medicinal herb Geranium wallichianum belongs to the family Geraniaceae. The East Asian Himalayas are its primary habitat. Overexploitation and overharvesting pose a threat to this plant, given its extensive ethnomedical utilization in the community. In Pakistan, its population has already declined by over 75%. Given its critical medicinal importance, urgent conservation efforts are needed to prevent extinction. The aim of the current research was to determine the effectiveness of sucrose and polyethylene glycol (PEG) in decelerating the growth of this medicinally important species. Nodal segments were utilized as explant with varying levels of polyethylene glycol (PEG) (0.5% and 1.5%) and sucrose (4% and 8%) as treatments on different growth attributes. Over a 45-day period, PEG treatments (0.5% and 1.5%) proved more efficient compared to sucrose in suppressing in vitro growth, with reduced shoot lengths (0.92 and 0.57 cm), dry weight (0.04 and 0.02 g), and fresh weight (0.06 and 0.04 g). PEG also significantly enhanced phenolic levels (0.96 and 0.19 mg/g) and soluble sugars (4.07 and 4.12 mg/g) while reducing total protein level (2.38 and 2.32 mg/g) and total chlorophyll content (0.17 and 0.14 mg/g). The Pearson correlation analysis showed a negative association between phenolic levels and total chlorophyll content, chlorophyll a, and chlorophyll b. The length of the shoot had a negative relationship with phenolic level but a positive relationship with both fresh and dry weight. The principal component analysis revealed that total sugars and phenolics that were grouped separately from other variables led to stronger responses to osmotic stress. These outcomes suggested that higher PEG was successful in reducing in vitro growth throughout short-term preservation in comparison to sucrose. The outcomes of this research could be applied for the in vitro conservation of medical plants in the future.

文摘Global warming has led to the frequent occurrence of extreme climatic events(ECEs)in the ecologically frag ile Qinghai-Xizang Plateau.Rural households face strong barriers in adaption,and food production is seriously threatened.Current methods for increasing household adaptability take a holistic point of view,but do not ac curately identify groups experiencing different adaptive barriers.To better identify different barriers,this paper examines natural,economic,cognitive,and technical barriers.A total of 17 indicators were selected to com prehensively evaluate the degree of barriers to crops adaptation in response to ECEs.Key factors were further analyzed to identify paths to break down the barriers.The results showed the following.(1)Natural barriers were present at the highest degree,economic barriers appear to be smallest,and the overall barriers were bi ased towards the lower quartile.10.82%of the households with the highest barriers.(2)67.38%of households report taking adaptive measures in crops production.The increase of the barriers leads to an increase and then a decrease in the possibility of adaptive behavior.(3)Addressing technical barriers is key to rapidly increasing household adaptive behavior in response to ECEs.The study provides recommendations for local governments to improve household adaptation behavior from two perspectives:short-term and long-term optimization path ways.This study can help governments quickly locate households with different classes of barriers,and propose more targeted adaptation policies.The ultimate goal is to ensure the sustainability of crops production and the well-being of households in northeastern part of the Qinghai-Xizang Plateau.

文摘PCR-SSCP was used to analyze the polymorphism of leptin gene in 539 samples of six cattle breeds, namely Nanyang （NY）, Qinchuan （QC）, Jiaxianred （JXR）, Xizhen （XZ）, Luxi （LX）, and Holstein cow （HOL） breeds. PCR products with a 330 bp were amplified and sequenced. The results showed that the frequencies of alleles A/B of NY, QC, JXR, XZ, LX, and HOL breeds were 0.558/0.442, 0.492/0.508, 0.571/0.429, 0.658/0.342, 0.591/0.409, and 0.615/0.385, respectively. The association of variations of leptin gene with growth traits in NY, QC, JXR breeds was analyzed. Some indexes of the individuals with genotype BB were higher than that with genotype AA and AB in NY breed, such as the indexes of body length, heart length, body weight, hucklebone width, body height, and average day gain. The height at hip cross of the individuals with genotype BB was higher than that of those with genotype AA and AB in QC breed （P 〈 0.05）. So leptin gene may be one of the candidate genes for growth traits with height at hip cross, but not for body weight, heart length, and body length trait. However, the height at hip cross and hucklebone width of the individuals with genotype AB and BB were higher than that of those with genotype AA in JXR breed （P 〈 0.05）, but the difference was not statistically significant in body weight and body sizes （body height, body length, and heart length）. And the polymorphisms in leptin gene were caused by G→T transversion at the 66th bp position, A→C transversion at the 67th bp position and G→T transversion at the 299th bp position. These results may be applied to marker-assisted selection of Chinese cattle breeds.
文摘The fish Sinocyclocheilus grahami is one of the indicative and endemic species in the Dianchi Lake ecosystem. As a result of pollution and invasion of exotic fishes, the fish had disappeared from Dianchi Lake since 1986 and only a few small populations survive in springs and streams around the lake. Due to the endangered status and special scientific value, S.grahami was listed as the second class protective animal of China in 1989. The importance of S. grahami and the indigenous biodiversity of Dianchi Lake were recognized by the Global Environment Foundation （GEF） /World Bank and Yunnan Development ＆ Reform Committee. Therefore a special grant was set up to restore and conserve the indigenous biodiversity of Dianchi Lake. The artificial breeding of S. grahami is a part of the targeted activities. Two successful breeding experiments were achieved using five females plus six males up to early March 2007. Approximately 1600 eggs were collected, of which 1320 eggs fertilized using the dry-fertilizing method. The mean fertilization rate was 73%. Approximately 480 fish fry was hatched and the mean hatching rate was 36%. After 10 days of cultivation, 95% fingerlings survived and their body lengths were up to 8- 12 mm. The importance of the artificial breeding success of S. grahami could be summarized as following： effectively protecting the fish from extinction; releasing the fish fry back to appropriate water body of the lake could help to restore the indigenous biodiversity of Dianchi Lake; facilitating the shift of local fish cultivation from the present non-indigenous to the future indigenous fishery.
