Genotypic variability for root/shoot parameters under water stress in some advanced lines of cotton (Gossypium hirsutum L.)

Research pertaining to genetic variability parameters, heritability, and genotypic, phenotypic, simple, and environmental correlations for various seedling traits in five elite advanced cotton (Gossypium hirsutum L.) lines (FH-113, FH-114, FH-941, FH-942, and FH-2015) and one check (CIM-496) was carried out during October and November 2010 under greenhouse conditions at the Cotton Research Institute (Faisalabad, Pakistan). Material was raised in plastic tubes with a randomized complete block design replicated three times. Three drought shocks were applied by withholding water from the tube-sown plants for 8-, 10-, and 12-day intervals. After 60 days of sowing, data on root/shoot traits like root length (cm), shoot length (cm), root weight (g), shoot fresh weight (g), lateral root number, root dry weight (g) shoot dry weight (g), and total plant weight (g) were recorded. Considerable genotypic variations existed between genotypes for all seedling characters. Higher broad-sense heritability estimates were found for all traits studied. Maximum broad-sense heritability coupled with high genetic advance in root length (0.99, 17.34), lateral root number (0.91, 2.89), and shoot length (0.90, 4.35) suggested a potential for genetic improvement through breeding and selection. The correlation coefficients among root length, shoot length, root dry weight, fresh shoot weight, and total plant weight were positively and significantly correlated; thus, they can be selected simultaneously as drought tolerance selection indexes owing to the absence of undesired relationships. Genotypes FH-942 and FH-113 had the lowest excised leaf water loss during the first 4 h and also for the next 4 h. Therefore, these two advanced lines (FH-942 and FH-113) with high initial water content and lower excised leaf water loss had better adaptation to water stress.

Insights into the Uses of Traditional Plants for Diabetes Nephropathy: A Review

Diabetic nephropathy (DN) is a serious kidney illness characterized by proteinuria, glomerular enlargement, reduced glomerular filtration, and renal fibrosis. DN is the most common cause of end-stage kidney disease, accounting for nearly one-third of all cases of diabetes worldwide. Hyperglycemia is a major factor in the onset and progression of diabetic nephropathy. Many contemporary medicines are derived from plants since they have therapeutic properties and are relatively free of adverse effects. Glycosides, alkaloids, terpenoids, and flavonoids are among the few chemical compounds found in plants that are utilized to treat diabetic nephropathy. The purpose of this review was to consolidate information on the clinical and pharmacological evidence supporting the use of a variety of medicinal plants to treat diabetic nephropathy.

Combining ability analysis for within-boll yield components in upland cotton (Gossypium hirsutum L.)

Cotton is an important cash crop worldwide, accounting for a large percentage of world agricultural exports; however, yield per acre is still poor in many countries, including Pakistan. Diallel mating system was used to identify parents for improving within-boll yield and fiber quality parameters. Combining ability analysis was employed to obtain suitable parents for this purpose. The parental genotypes CP-15/2, NIAB Krishma, CIM-482, MS-39, and S-12 were crossed in complete diallel mating under green house conditions during 2009. The F₀ seed of 20 hybrids and five parents were planted in the field in randomized complete block design with three replications during 2010. There were highly significant differences among all F₁ hybrids and their parents. Specific combining ability (SCA) variance was greater than general combining ability (GCA) variance for bolls per plant (9.987), seeds per boll (0.635), seed density (5.672), lint per seed (4.174), boll size (3.69), seed cotton yield (0.315), and lint percentage (0.470), showing predominance of non-additive genes; while seed volume (3.84) was controlled by additive gene action based on maximum GCA variance. Cultivar MS-39 was found to be the best general combiner for seed volume (0.102), seeds per boll (0.448), and lint per seed (0.038) and its utilization produced valuable hybrids, including MS-39 x NIAB Krishma and MS-39 x S-12. The parental line CIM-482 had high GCA effects for boll size (0.33) and seeds per boll (0.90). It also showed good SCA with S-12 and NIAB Krishma for bolls per plant, with CP- 15/2 for boll size, and with MS-39 for seeds per boll. The hybrids, namely, CP-15/2 x NIAB Krishma, NIAB Krishma x S-12, NIAB Krishma x CIM-482, MS-39 x NIAB Krishma, MS-39 x CP-15/2, and S-12 x MS-39 showed promising results. Correlation analysis revealed that seed cotton yield showed significant positive correlation with bolls per plant, boll size and seeds per boll while it showed negative correlation with lint percentage and lint per seed. Seed volume showed significant negative correlation with seed density. Seeds per boll were positively correlated with boll size and negatively correlated with bolls per plant lint percentage and lint per seed. Similarly, lint per seed exhibited positive correlation with lint percentage and boll size showed significantly negative correlation with bolls per plant. Presence of non-additive genetic effects in traits like bolls per plant, seeds per boll, lint per seed, seed cotton yield, and lint percentage is indicative of later generation selection or heterosis breeding may be adopted. For boll size, seed volume and seed density early generation selection may be followed because of the presence of additive gene action. The parental material used in this study and cross combinations obtained from these parents may be exploited in future breeding endeavors.

Insights into the Protective Effects of Thymoquinone against Toxicities Induced by Chemotherapeutic Agents

The drugs used to treat cancer not only kill fast-growing cancer cells, but also kill or slow the growth of healthy cells, causing systemic toxicities that lead to altered functioning of normal cells. Most chemotherapeutic agents have serious toxicities associated with their use, necessitating extreme caution and attention. There is a growing interest in herbal remedies because of their pharmacological activities, minimal side effects, and low cost. Thymoquinone, a major component of the volatile oil of Nigella sativa Linn, also known as black cumin or black seeds, is commonly used in Middle Eastern countries as a condiment. It is also utilized for medicinal purposes and possesses antidiabetic, anti-cancer, anti-inflammatory, hepatoprotective, anti-microbial, immunomodulatory, and antioxidant properties. This review attempts to compile the published literature demonstrating thymoquinone's protective effect against chemotherapeutic drug-induced toxicities.

In vitro utilization of lime treated olive cake as a component of complete feed for small ruminants

AIM

The current in vitro study was carried out to determine the chemical composition and inclusion level of lime treated olive cake on acid detergent fiber (ADF) replacement basis in adult male goats.

MATERIALS AND METHODS

Crude olive cake was collected and evaluated for proximate composition and protein fractionation. It was treated with 6% lime and incubated for 1 week under room temperature in 2 kg sealed polythene bags and was evaluated for proximate composition after incubation. Different isonitrogenous complete diets containing 0-50% of lime treated olive cake on ADF replacement basis were formulated as per the requirement of adult male goats. In ADF replacement, fiber and concentrate sources were replaced by lime treated olive cake by replacing the 0-50% ADF percentage of the total 40% ADF value of complete feed. The formulated complete diets were tested for in vitro degradation parameters.

RESULTS

Treatment of olive cake with 6% slaked lime increased availability of cellulose and alleviated digestibility depression caused by high ether extract percentage. Organic matter, nitrogen free extract, ADF and neutral detergent fiber were significantly lowered by lime treatment of olive cake. The cornell net carbohydrate and protein system analysis showed that non-degradable protein represented by acid detergent insoluble nitrogen (ADIN) was 21.71% whereas the non-available protein represented by neutral detergent insoluble nitrogen (NDIN) was 38.86% in crude olive cake. The in vitro dry matter degradation (IVDMD) values were comparable at all replacement levels. However, a point of inflection was observed at 40% ADF replacement level, which was supported by truly degradable organic matter (TDOM), microbial biomass production (MBP), efficiency of MBP and partitioning factor values (PF).

CONCLUSION

In our study, we concluded that there is comparable difference in composition of Indian olive cake when compared with European olive cake. The most important finding was that about 78% of nitrogen present in Indian olive cake is available to animal in contrary to that of European olive cake. We concluded from in vitro studies that Indian olive cake can be included in complete feed at 30% level (w/w; 40% ADF replacement) for feeding in small ruminants without compromising in vitro degradability of the feed.

Polypharmacy in chronic liver disease patients: Implications for disease severity, drug-drug interaction, and quality of life

Multiple prescriptions for different medications may be needed for chronic conditions, increasing the risk of polypharmacy. The WHO defined polypharmacy as "the administration of many drugs at the same time or the administration of an excessive number of drugs". The primary goal of this study was to evaluate polypharmacy in patients with chronic liver disease and to identify potential drug-drug interactions associated with it. A cross-sectional study was conducted at a tertiary care hospital in Mangalore, Karnataka, for six months, from November 2020 to April 2021. The study involved 118 patients with chronic liver disease from various age groups. Data was gathered by analyzing patients' medical records kept on the ward and interviewing them individually. In admission and discharge prescriptions, polypharmacy was examined. Online interaction checkers from Drugs.com and Medscape were used to interpret potential drug-drug interactions. The SF-36 and Chronic Liver Disease Questionnaire were used to measure the quality of life. The data obtained were analyzed statistically to determine the significant correlation. The number of prescribed drugs was significantly correlated (P = 0.018) with the severity of liver disease in Child-Pugh categories B and C. Additionally, moderate polypharmacy reduced quality of life (P < 0.05), and the physical health category was significantly associated with disease severity (P < 0.05). Drug-drug interactions were found in 108 out of the 118 examined prescriptions, totaling 586 interactions in the admission list and 405 interactions in the discharge list. If the potentially serious main drug interaction identified in this study is not well monitored, it could lead to a serious, potentially fatal health condition. Despite being advised, safety is not always guaranteed by liver enzyme monitoring. Therefore, healthcare providers must take additional precautions to avoid inappropriate prescribing, minimize side effects, and ensure drug safety.

Efficacy of Thymoquinone and Hesperidin in Attenuating Cardiotoxicity from 5-Fluorouracil: Insights from In Vivo and In Silico Studies

5-Fluorouracil (5-FU) is widely used in chemotherapy but poses serious risks of cardiotoxicity, which can significantly affect treatment outcomes. Identifying interventions that can prevent these adverse effects without undermining anticancer efficacy is crucial. This study investigates the efficacy of Thymoquinone (TQ) and Hesperidin (HESP) in preventing cardiotoxicity induced by 5-FU in Wistar rats and elucidates the molecular interactions through docking studies. We employed an experimental design involving multiple groups of Wistar rats exposed to 5-FU, with and without the concurrent administration of TQ and HESP. Cardiac function markers, oxidative stress indicators, and inflammatory markers were assessed. Additionally, molecular docking was used to analyze the interaction of TQ and HESP with key inflammatory proteins. Treatment with TQ and HESP not only lowered levels of cardiac enzymes but also improved antioxidant capacity and reduced inflammation in cardiac tissues. Notably, the combination of TQ and HESP provided more significant protective effects than either agent alone. Molecular docking supported these findings, showing effective binding of TQ and HESP to inflammatory targets. TQ and HESP demonstrate potential as protective agents against cardiotoxicity in 5-FU-treated rats, with their combined use offering enhanced protection. These findings suggest a viable strategy for reducing cardiac risks associated with 5-FU chemotherapy.

Effect of Idebenone, Resveratrol and Taurine on the Sperm Quality and Lipid Peroxidation of Cryopreserved Crossbred Ram Semen

BACKGROUND

Antioxidants reduce oxidative stress and improve sperm quality during cryopreservation.

OBJECTIVE

To investigate the effect of idebenone, resveratrol and taurine on the sperm quality and lipid peroxidation of cryopreserved crossbred ram semen.

METHODS

In a split study, pooled ejaculates were divided into four aliquots cryopreserved in tris extender with no antioxidant (control), with idebenone (0.01 mM), resveratrol (0.1 mM), and taurine (40 mM).

RESULT

Among all antioxidants, taurine treatment yielded significantly better sperm quality. Malondialdehyde (MDA) level in seminal plasma was significantly lower for taurine compared to the control, idebenone and resveratrol treatments. Moreover, sperm quality declined significantly in all the groups from pre-freeze to post-thaw.

CONCLUSION

The findings indicate that taurine at 40 mM significantly improves sperm quality compared to 0.01 mM idebenone and 0.1 mM resveratrol, hence it can be considered as a potent and promising antioxidant supplement in tris extender for the cryopreservation of crossbred ram semen.
