Effect of Neem Oil on Sperm Mitochondrial Activity

It is a known fact that neem oil has some effect on motility of sperm. Motility of sperm depends on mitochondrial activity present in mid-piece of sperm. In the present study, the mitochondrial activity of sperm was evaluated after treating semen with the different quantities of neem oil. The mitochondrial activity was also evaluated after subjecting the semen samples for different incubation periods keeping the quantity of semen as well as that of neem oil same. Tests were done on thirty normozoospermic semen samples with motile score more than 75%. It was found that as the quantity of neem oil increases, the mitochondrial activity decreases significantly (P < 0.001). Similar results were found, when same quantity of neem oil was treated with same quantity of semen, but incubating for different time durations. The mitochondrial activity decreases significantly (P < 0.001) from one minute to twenty minutes. So, it indicates that as the contact period between neem oil and semen increases the mitochondrial activity decreases significantl

Incorporating Deep Q -- Network with Multiclass Classification Algorithms

In this study, we explore how Deep Q-Network (DQN) might improve the functionality of multiclass classification algorithms. We will use a benchmark dataset from Kaggle to create a framework incorporating DQN with existing supervised multiclass classification algorithms. The findings of this study will bring insight into how deep reinforcement learning strategies may be used to increase multiclass classification accuracy. They have been used in a number of fields, including image recognition, natural language processing, and bioinformatics. This study is focused on the prediction of financial distress in companies in addition to the wider application of Deep Q-Network in multiclass classification. Identifying businesses that are likely to experience financial distress is a crucial task in the fields of finance and risk management. Whenever a business experiences serious challenges keeping its operations going and meeting its financial responsibilities, it is said to be in financial distress. It commonly happens when a company has a sharp and sustained recession in profitability, cash flow issues, or an unsustainable level of debt

Review on Rasayana therapy to improve immunity for better health

Ayurvedic medicine has many rejuvenating herbs, traditionally known as Rasayana, which improve health, immunity, vigor, vitality and longevity, as well as protect against stress and help in boosting immunity power. Rasayana Chikitsa (rejuvenation) is a inimitable branch of Ayurveda. The word “Rasayana” means the way for attaining excellent Rasadi Dhatus. In Ayurveda, one of the major methods of presentation of positive health has been described i.e. Rasayana. This resistance power of the body, which prevents the development of diseases, is called as Immunity or Vyadhikshamatva. The ultimate aim of Rasayan therapy is to correct dosha disturbances and improve Agni and Dhatu function which overall improves strength, immunity. Basically, the application of Rasayan therapy comes in the perspective of premature ageing (Jara) and death. Rasayanas are used as preventive, curative and health promotive purpose

Metabolism of Dietary and Microbial Vitamin B Family in the Regulation of Host Immunity

Vitamins are micronutrients that have physiological effects on various biological responses, including host immunity. Therefore, vitamin deficiency leads to increased risk of developing infectious, allergic, and inflammatory diseases. Since B vitamins are synthesized by plants, yeasts, and bacteria, but not by mammals, mammals must acquire B vitamins from dietary or microbial sources, such as the intestinal microbiota. Similarly, some intestinal bacteria are unable to synthesize B vitamins and must acquire them from the host diet or from other intestinal bacteria for their growth and survival. This suggests that the composition and function of the intestinal microbiota may affect host B vitamin usage and, by extension, host immunity. Here, we review the immunological functions of B vitamins and their metabolism by intestinal bacteria with respect to the control of host immunity

Evaluation of nutritive value of local fishes in Wani region, Dist. Yavatmal, (Maharashtra state)

In the present investigation an attempt has been made to evaluate nutritive values of local fishes available in Wani area from Nirguda river and Wardha river. The present study was carried out during the period of Nov. 2008 to Oct. 2009. During study the survey, collection, identification and biochemical analysis of local fishes was done.The results of present study showed that all the fishes were rich in protein content, maximum protein content found in Anguilla bengalensis 29.34 % and minimum found in Punctius curmuca 10.34 %.  Lipid contents of fishes were low and varied from 1.23 % in Rasbora daniconius to 6.54 % in Heteropneustes fossilis Glycogen content of fishes were negligible and varies from 0.11 % in Ostebrama cotio to 0.090% in Cyprinus carpio.

Some reproductive studies in Clarias batrachus with reference to different thermal conditions

Eco-physiological study indicates the Clarias batrachus is a eurythermal fish and able to tolerate the wide range of climatic conditions. The quantitative analysis of nutritional components in gonadal region, such as glucose, proteins and fats showed the variations during exposure of fish to hot and cold temperatures. The fresh water catfish exhibits distinct phases of reproduction and also showed the changes in the levels of energy precursors with change in the excretory products, with respect to adaptability towards different environmental temperature conditions. Gradual increase of glucose, proteins, and cholesterol is observed in the male gonadal tissues. Rectal gland and clasper tissues showed, decreased of urea levels during the exposure of fish to the higher tolerable temperature. However, in female fish, the levels of proteins are significantly enhanced during the high temperature exposure. The levels of urea significantly decreased in the tissues of uterus and brain during the study period, while the lowering of glucose levels in brain indicates the extent of rate of physiological activity of the brain

Cytogenetic Analysis in Domestic Cats

The present study comprised of 25 blood samples from domestic cats were  cultured in duplicates for comparing efficacy of two mitogens i.e. Concanvalin A and Lectin.  Concanvalin A was found to be significantly superior to Lectin. GTG- banding was used for preparation of domestic cat karyograms. Diploid number of chromosomes in domestic cats were found to 2n = 38 consisting of 18 pairs of autosomes and 1 pair of sex chromosomes. The 18 pairs of autosomes were classified into 5 groups as A,B,C,D,E, and F consisting of autosome pairs as Large submetacentric 3 pairs, Large subtelocentrics 4 pairs, Large metacentrics 2 pairs, Small submetacentric and subtelocentrics 4 pairs, Small metacentrics2 pairs and Telocentric or acrocentric 2 pairs, respectively. Whereas ‘X’ chromosome was found to be medium sized subtelomeric and ‘Y’ chromosome was small areocentric.  No major significant abnormalities were reported in the present investigation

A taxonomic and phylogenetic revision of the Penicillium sclerotiorum complex

The morphological concept of Penicillium sclerotiorum (subgenus Aspergilloides) includes strains with monoverticillate, vesiculate conidiophores, and vivid orange to red colony colours, with colourful sclerotia sometimes produced. Multigene phylogenetic analyses with the nuclear ribosomal internal transcribed spacer (ITS) region, cytochrome c oxidase subunit 1 (cox1), β-tubulin (benA), translation elongation factor 1-α (tef1-α), and calmodulin (cmd), reveal that the P. sclerotiorum morphospecies is a complex of seven phylogenetically distinct species, three of which were recently described, namely P. guanacastense, P. mallochii, and P. viticola. Three previously unidentified species are described here as P. cainii, P. jacksonii, and P. johnkrugii. The phylogenetic species are morphologically similar, but differ in combinations of colony characters, sclerotium production, conidiophore stipe roughening and branching, and conidial shape. Ecological characters and differences in geographical distribution further characterise some of the species, but increased sampling is necessary to confirm these differences. The fungal DNA barcode, the ITS, and the animal DNA barcode, cox1, have lower species resolving ability in our phylogenetic analyses, but still allow identification of all the species. Tef1-α and cmd were superior in providing fully resolved, statistically well-supported phylogenetic trees for this species complex, whereas benA resolved all species but had some issues with paraphyly. Penicillium adametzioides and P. multicolor, considered synonyms of P. sclerotiorum by some previous authors, do not belong to the P. sclerotiorum complex
