Published: March 2024

Background: Assam is blessed with over 200 fish species. The perceptions of fish farmers in Nalbari and Barpeta districts of central Assam regarding the opportunities and challenges of utilizing indigenous fish species (IFS) for aquaculture have been discussed.
Methodology: Utilizing a combination of purposive and random sampling techniques, data was collected from 120 fish farmers across Barpeta and Nalbari districts. Pertinent information was gathered from fish farmers (n=240) combined in the districts of Barpeta and Nalbari. To rank the causal factors based on the responses from the respondents, subsequently calculate the Rank Based Quotient (RBQ).
Results and Discussion: High demand, market value, and potential returns as key prospects driving farmer preferences for indigenous fish species cultivation. However, high capital investment, inadequate technical support, flood, quality seed etc. were found as significant challenges in the study areas. These factors are negatively impacting farmers, hindering their ability to achieve anticipated fish yields and income. The study focused on addressing these challenges through integrated, multidisciplinary management plan on resource conservation together with geo-environmental, eco-biological and socio-cultural integrity.

Forkhead-associated phosphopeptide binding domain 1 (FHAD1) deficiency impaired murine sperm motility
Authors: Zhang Xi , Xue Jiangyang , Jiang Shan , Zheng Haoyu , Wang Chang 
Published: March 2024

Background
Genetic knockout-based studies conducted in mice provide a powerful means of assessing the significance of a gene for fertility. Forkhead-associated phosphopeptide binding domain 1 (FHAD1) contains a conserved FHA domain, that is present in many proteins with phospho-threonine reader activity. How FHAD1 functions in male fertility, however, remains uncertain.

Methods
Fhad1−/− mice were generated by CRISPR/Cas9-mediated knockout, after which qPCR was used to evaluate changes in gene expression, with subsequent analyses of spermatogenesis and fertility. The testis phenotypes were also examined using immunofluorescence and histological staining, while sperm concentrations and motility were quantified via computer-aided sperm analysis. Cellular apoptosis was assessed using a TUNEL staining assay.

Results
The Fhad1−/−mice did not exhibit any abnormal changes in fertility or testicular morphology compared to wild-type littermates. Histological analyses confirmed that the testicular morphology of both Fhad1−/−and Fhad1+/+ mice was normal, with both exhibiting intact seminiferous tubules. Relative to Fhad1+/+ mice, however, Fhad1−/−did exhibit reductions in the total and progressive motility of epididymal sperm. Analyses of meiotic division in Fhad1−/−mice also revealed higher levels of apoptotic death during the first wave of spermatogenesis.

Discussion
The findings suggest that FHAD1 is involved in both meiosis and the modulation of sperm motility.

A field study was conducted to know the “Effect of phosphate solubilizing microorganisms and phosphorus levels on growth, yield and quality of chickpea (Cicer arietinum L.) in inceptisol.” The experiment was laid in Factorial Randomized Block Design (FRBD) with sixteen treatments, replicated thrice during rabi season of 2019-20 at the Department Research Farm of SSAC, College of Agriculture, Latur. The treatments comprises four main (absolute control, Bacillus megaterium, Aspergillus niger and Aspergillus awamori @ 10 ml kg-1 seed treatment) and four sub treatments (0,45,60 and 75 P2O5 kg ha-1). The results indicated that, the incorporation of phosphate solubilizing microorganisms viz. Aspergillius awamori @ 10 ml kg-1 seed in combination with soil application of 75 P2O5 kg ha-1 found to be effective in improving growth and yield attributing characters viz. number of root nodules, fresh and dry weight, chlorophyll content , grain yield and straw yield as compared to Aspergillus niger and Bacillus megaterium along with 60 P2O5 kg ha-1 and over control. Further results revealed that test weight and protein percentage was significantly influenced with the seed treatment of Aspergillius awamori @ 10 ml kg-1 seed in combination with application of 75 P2O5 kg ha-1.
Strong postcranial size dimorphism in Australopithecus afarensis: Results from two new resampling methods for multivariate data sets with missing data
Authors: Gordon Adam D. , Green David J. , Richmond Brian G. 
Published: November 2007

AbstractThere is considerable debate over the level of size dimorphism and inferred social behavior of Australopithecus afarensis. Most previous studies have analyzed size variation in single variables or multiple variables drawn from single elements. These approaches suffer from small sample sizes, underscoring the need for new techniques that incorporate measurements from multiple unassociated elements, reducing the influence of random sampling on size variation in fossil samples. One such technique, the template method, has recently been proposed but is limited to samples with a template specimen and is sensitive to a number of assumptions. Here we present two new resampling methods that do not require a template specimen, allow measurements from multiple unassociated elements to be included in a single analysis, and allow for significance tests between comparative and fossil multivariate data sets with missing data. Using these new methods, multivariate postcranial size dimorphism is measured using eight measurements of the femur, tibia, humerus, and radius in samples of A. afarensis, modern humans, chimpanzees, gorillas, and orangutans. Postcranial dimorphism in A. afarensis is similar to that of gorillas and orangutans, and significantly greater than in modern humans and chimpanzees. Because studies in living primates have examined the association of behavior with dimorphism in body mass and craniodental measurements, not postcrania, relationships between postcranial dimorphism and social behavior must be established to make robust behavioral inferences for A. afarensis. However, the results of this and past studies strongly suggest behavioral and mating strategies differed between A. afarensis and modern humans. Am J Phys Anthropol, 2008. © 2007 Wiley‐Liss, Inc.
Quantitative Conformational Study of Redox‐Active [2]Rotaxanes, Part 2: Switching in Flexible and Rigid Bistable [2]Rotaxanes
Authors: Nikitin Kirill , Lestini Elena , Stolarczyk Jacek K. , Müller‐Bunz Helge , Fitzmaurice Donald 
Published: November 2007

AbstractTranslational movement of the macrocycle in two structurally similar bistable [2]rotaxanes, which is induced by a four‐step electrochemical process in solution, has been investigated by using a methodology developed in the preceding article (Chem. Eur. J. 2008, 14, 1107–1116). Both [2]rotaxanes contain a crown ether that can be accommodated by either of two interconnected viologen recognition sites. These sites are substantially different in terms of their affinity towards the crown ether and they possess considerably different electrochemical reduction potentials. The two [2]rotaxanes differ in the length and the rigidity of a bridge that links these sites. A combination of molecular mechanics modelling and NOE spectroscopy data provides information about the conformations of both [2]rotaxanes in the parent oxidation state when the crown ether exclusively populates the strong recognition site. To determine the population of the recognition sites at subsequent stages of reduction, a paramagnetic NMR technique and cyclic voltammetry were used. The key finding is that the flexibility of the connecting bridge element between the recognition sites interferes with shuttling of the crown ether in [2]rotaxanes. It can be demonstrated that the more flexible trimethylene bridge is folded, thus limiting the propensity of the crown ether to shuttle. Consequently, the crown ether populates the original site even in the second reduced state of the flexible [2]rotaxane. On the contrary, in the [2]rotaxane in which two viologen sites are connected by a larger and more rigid p‐terphenylene bridge, the predominant location of the crown ether at the weak recognition site is achieved after just one single electron reduction.
SIRT2, tubulin deacetylation, and oligodendroglia differentiation
Authors: Tang Bor Luen , Chua Christelle En Lin 
Published: November 2007

AbstractThe mammalian silent information regulator 2 (SIRT2) is an NAD‐dependent histone deacetylase with known roles in the regulation of the cell cycle. SIRT2 is also a tubulin deacetylase functioning as an early mitotic checkpoint, but its roles in regulating cytoplasmic microtubule dynamics were unknown. Novel findings now indicate that SIRT2 is specifically enriched in brain oligodendroglia, where it functions specifically in modulating the oligodendrocyte cytoskeleton during its differentiation and maturation.

Nuclear protein contents in peripheral blood mononuclear cells of trisomy 21 infants
Authors: Hamurcu Zuhal , Demirtas Halil , Patiroğlu Türkan , Kumandas Sefer 
Published: November 2007

AbstractObjectiveThe trisomy 21 (Ts21) or Down's syndrome (DS) phenotype is assumed to occur primarily by the expression/overexpression of some genes encoded by the extra chromosome 21. It has recently been shown by AgNOR staining that babies with Ts21 have more AgNOR area (more NOR proteins) and more RNA content in their peripheral blood mononuclear cells (PBMCs) than those of controls. The aim of this study was to test whether or not the nuclear proteins content of PBMCs from trisomy 21 babies/infants is higher than that of the controls.MethodFor this purpose, flow cytometric measurement of the stained PBMC nuclei was used. Nuclei from PBMCs was isolated and stained with propidium iodide and fluorescein isothiocyanate (PI/FITC) for DNA and protein estimation, respectively.ResultsMean nuclear protein content of Ts21's (N = 30, mean age = 3.46 ± 3.05 years old) PBMCs was found statistically higher than that of the controls (N = 33, mean age = 3.79 ± 1.93 years old) (P = 0.005, nonparametric Mann–Whitney U test for two independent variables). This means that the average nuclear protein content of PBMC from Ts21 infants is higher than that of the controls. Furthermore, there is a moderate negative correlation between the ages of the studied DS patients and the protein content in the nuclei of their PBMCs (Linear regression analysis: P = 0.002, r = −0.55). This correlation is not found with controls (P = 0.186, r = −0.24).ConclusionWe have concluded that average protein content of PBMCs' nuclei from DS infants is higher than that of the controls, decreasing significantly with age. © 2007 Clinical Cytometry Society
