Soil salinity is one of the most severe factors limiting growth and physiological response in cowpea plants. In the present study, the effect of rhizobacterium strains BR2 and BR3 on the growth of cowpea (Vigna unguiculata L.) varieties—Pusa Sukomal and RC101—tolerance to 0, 25, 50, and 75 mM concentrations of NaCl salinity was evaluated. The rate of growth, in general, was high in plants irrigated with 25 mM NaCl saline water as compared to control, and thereafter, the growth reduced with increase in salinity concentrations. The results revealed that treating the seeds with rhizobacteria accompanied by NaCl salinity increased growth parameters of the cowpea plant as compared to the seeds irrigated with sodium chloride alone. Treatment with rhizobacteria mitigated the harmful effect of NaCl, and the growth was significantly better than the plants growing in saline water without rhizobacterium inoculation. The overall performance of Pusa Sukomal with BR3 strain was found to be better than the other combinations tested. Flowering in field plants started within 45 days of sowing, and the seeds in plants irrigated with saline water, in the presence of rhizobacterium, were found to be healthy as compared to control seeds. Seed protein profile was analyzed by SDS PAGE gel studies.

Changes in consumption behavior to instant food cause various health problems, such as obesity, dislipidemia, and atherosclerosis. A study was conducted to investigate Moringa oleifera extract as an anti-inflammation product that decreases the levels of biochemical markers IL-1 and TNF-a. This experiment was done with randomized pre- and posttest control-group design, employing 40 Wistar rats separated into five groups: control group 0% M. oleifera leaf extract (P0), treatment group 1 with 10% M. oleifera leaf extract (P1), treatment group 2 with 15% M. oleifera leaf extract (P2), treatment group 3 with 20% M. oleifera leaf extract (P3), and treatment group 4 with 25% M. oleifera leaf extract (P4). This research observed that intake of 20% M. oleifera leaf extract results in the highest significant decrease of 15.42% of IL-1 level (134.64 6 1.98 to 113.87 6 4.30 pg/mL) and decrease of 45.63% of TNF-α level (28.62 6 1.25 to 15.56 6 7.20 pg/mL). Therefore, it can be concluded that intake of M. oleifera leaf extract by Wistar rat has anti-inflammatory effects on chronic dyslipidemia through decrease of IL-1 and TNF-α levels and histopathology profile. Further research is required to determine whether the application of M. oleifera leaf extract (daun kelor) in humans will have similar anti-inflammation effects.

Cognitive dysfunction including dementia is a common complication of chronic kidney disease (CKD) that has just been recently appreciated. It has negative outcomes in the management of patients with CKD. This study explored the possible biochemical and clinical features of patients with CKD that can predict the occurrence of cognitive impairment in patients with moderate to severe CKD. We evaluate patients with stages 3-5 CKD for the occurrence and predictors of cognitive impairment. Multiple areas of cognitive function were tested in this single-center study using Community Screening Interview for Dementia (CSID) and Trial-Making Test A (TMTA)/Trial-Making Test B (TMTB). Cognitive impairment was correlated with patients’ routine biochemical, hematological, and selected clinical parameters. We observed a negative correlation between cognitive impairment and patient’s serum calcium (r 5 0.240; p 5 0.033) and estimated Glomerular filtration rate (eGFR) (r 5 0.379; p 5 0.0006). Therefore, eGFR is an accurate predictor of cognitive dysfunction in patients with moderate to severe CKD. Early evaluation of cognitive function in CKD is indeed advised for optimal outcome in the management of patients with CKD.

The prevalence of parasitic infections such as malaria, which leads to decrease in hematological indices, the major cause of anemia, constitutes a serious health challenge in many developing countries such as Nigeria. This study investigated the effect of methanol seed extract of Aframomum melegueta on selected hematological indices of 2,4-dinitrophenylhydrazine (2,4-DNPH)-induced anemic rats model. The toxicity study and qualitative phytochemical screening of the extract were carried out using standard procedure. Twenty Wistar rats were grouped into five of four rats each (n 5 4). Group I: Normal control; Group II: Negative control; Group III: administered 20 ml/kg b.w. of Astifer (Standard drug); Group IV and V were administered 200 and 400 mg/kg b.w. of the extract, respectively. The animals of Groups II to V were induced with 2,4-dinitrophenylhydrazine (20 mg/kg b.w.) once daily for seven consecutive days; their blood samples were collected by ocular puncture into heparinized capillary tubes for hematological analysis and animals with packed cell volume (PCV) 30% reduction were considered anemic for the study. The result of the qualitative phytochemical analysis showed that the methanol extract tested positive to alkaloids, carbohydrate, saponins, flavonoids, steroids, terpenoids, and anthraquinones. Acute toxicity and lethality studies on methanol extract showed an oral LD50 equal or less than 5000 mg/kg b.w. in mice. The rats administered 20 ml/kg b.w. of Astifer showed significant (P 0.05) increase in PCV, hemoglobin, red blood cell (RBC) count, white blood cell (WBC) count, and neutrophils count compared with the normal control animals. The rats administered 200 mg/kg b.w. of A. melegueta showed significantly (P 0.05) higher PCV and WBC count; non significant (P 0.05) decrease in hemoglobin count, RBC, platelet, neutrophils and lymphocyte count compared with the normal control animals. The rats administered 400 mg/kg b.w. of A. melegueta showed significant (P 0.05) increase in hemoglobin, platelet, erythrocyte sedimentation rate (ESR) and neutrophils count; non significant (P 0.05) lower PCV, RBC, WBC count, and lymphocyte count compared with anemic rats administered with 0.3 ml of normal saline. It can be concluded that Aframomum melegueta seed has beneficial immunological and hematological properties in Wistar rats and possessed erythropoietic potentials at minimal dose that support its use for treating anemia.

Type 2 diabetes mellitus (T2DM) is one of the threatening disorders in the world. It affects people of all ages. Type 2 diabetes mellitus is a condition in which the glucose level in the blood is elevated due to improper function of the secretion of insulin from beta cells of the pancreas. It is a multifactorial disease because it is caused by both environmental and hereditary factors. One of the genes which play an important role in type 2 diabetes mellitus is SLC30A8 which encodes for zinc transporter ZnT8. The common polymorphic site for SLC30A8 is rs13266634. This single-nucleotide polymorphism leads to type 2 diabetes mellitus by replacing the arginine residue with tryptophan residue. This review mainly focuses on the polymorphic studies in the gene SLC30A8 and its association with type 2 diabetes mellitus.

Pollution in water bodies and soil is a major and ever-increasing environmental issue nowadays, and most conventional remediation approaches do not provide appropriate solutions. The contamination of soil is a major concern for the environment and needs to be remediated. These pollutants include complex organic compounds, heavy metals released from industries and plants and natural products such as oils from accidental release. Further the nature of pollution will be governed by the source and type of the contaminant, and other inorganic compounds are released into the environment from a number of sources like mining, smelting, electroplating, and farming. Plants can clean up many types of contaminants like metals, pesticides, oils, and explosives. Phytoremediation is emerging as a bio-based and low-cost alternative in the cleanup of heavy metal-contaminated soils.

In this study, the effect of extraction parameters (ethanol concentration, sonication time, and solvent-to-sample ratio) on Ficus deltoidea leaves was investigated using ultrasound-assisted extraction by response surface methodology (RSM). Total phenolic content (TPC) of F. deltoidea extracts was identified using Folin-Ciocalteu method and expressed in gallic acid equivalent (GAE) per g. Box-Behnken statistical design (BBD) was the tool used to find the optimal conditions for maximum TPC. Besides, the extraction yield was measured and stated in percentage. The optimized TPC attained was 455.78 mg GAE/g at 64% ethanol concentration, 10 minutes sonication time, and 20 mL/g solvent-to-sample ratio whereas the greatest extraction yield was 33% with ethanol concentration of 70%, sonication time of 40 minutes, and solvent-to-material ratio at 40 mL/g. The determination coefficient, R2, for TPC indicates that 99.5% capriciousness in the response could be clarified by the ANOVA model and the value of 0.9681 of predicted R2 is in equitable agreement with 0.9890 of adjusted R2. The present study shows that ethanol-water as solvent, a short time of 10 minutes, and adequate solvent-to-sample ratio (20 mL/g) are the best conditions for extraction.

The present research is a biological screening of Eichornia crassipes (Pontederiaceae). Dichloromethane and methanol extracts of the whole plant were investigated for their antibacterial, antifungal, phytotoxic, and cytotoxic activities. The antibacterial activity was evaluated using agar well-diffusion method against Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Shigella flexneri, Pseudomonas aeruginosa, and Salmonella typhi. The antifungal activity was evaluated using the agar tube–dilution method against Candida albicans, Candida glabrata, Aspergillus flavus, Microsporum canis, and Fusarium solani. The phytotoxicity activity was determined using Lemna bioassay against Lemna minor. Brine shrimp– cytotoxicity assay was determined against brine-shrimp larvae. Dichloromethane extract exhibited significant phytotoxicity (100% growth regulation) at 1,000 μg/ml concentration against Lemna minor whereas methanolic extracts showed moderate (75% growth regulation) phytotoxicity at the same concentration. Methanolic extract showed cytotoxicity at the highest level of dose whereas dichloromethane extract showed no activity having Etoposide as standard drug. Both of the extracts have nonsignificant antifungal and antibacterial activity.
