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.

There is no existence of life without plants. Plants are the essential foundation of medicine. Some important drugs that are still in use today are derived from traditional medicinal herbs. The hunt for new medicines has engaged ethnobotany and ethnopharmacology—a new route as an important source of knowledge, which led toward different sources and classes of compounds. Nowadays, studies on structure-activity relationships, and their impact on the design of novel drugs have rendered them one of the utmost valuable and thus significant accomplishments of pharmacochemistry, an advance constituent in the group of pharmaceutical sciences. In this paper, we have discussed the historical importance of medicinal plants, geographical importance throughout the world, some important historical observations of medicinal plants, and leading drugs of plant origin which are still being used to treat various ailments, with or without any structural modifications.

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.

Charcoal hemoperfusion (CHP) is one of the extracorporeal removal techniques that are used to remove toxins from the body. CHP generally is considered the preferred method for extracorporeal extraction of several toxins—toxins that are adsorbed by activated charcoal. Assessments of the tannic acid’s protective effects on ophidian poisoning are associated with the toxic proteins’ precipitation by tannic acid. The challenge in treating a snakebite lies in removing the injected poison with minimal damage to blood constituent proteins. An alternative is CHP, and this investigation proposed to develop a column for hemoperfuser cartridge, combining charcoal granules trapped between layers of polymeric material conjugated to tannic acid, using an in vitro model scaled to the Wistar rat, which can be tested in an animal model. The cartridge was evaluated using the 22 full factorial design, in duplicate, as a method to study the effects of granulated-charcoal size and tannic acid concentration on the hematologic profile (platelet and leukocyte counts) and biochemical profile (total serum protein and albumin dosages) of sheep blood. The results demonstrate that charcoal in hemoperfuser cartridge: (1) decreases the serum in sheep blood volume, as consequence, (2) increases the serum proteins’ concentration, and (iii) exerts slight influence on albumin. The inclusion of tannic acid in hemoperfuser column precipitates some of serum proteins and albumin, decreasing their concentrations in the plasma serum. In conclusion, based on these effects we can suggest the use of 0.02 g tannic acid concentration and 8–20 mesh granulated charcoal in hemoperfuser cartridge for precipitating toxic proteins from snake venoms.

The aim of this study is to compare the use of plant-based insect repellents that are environment friendly with the use of insect repellents based on chemical substances which can be harmful to the environment and human health. The plant studied here is “tea tree”; its scientific name is Melaleuca alternifolia. Essential oil from this plant is extracted by steam distillation method. Based on the previous research, tea tree oil has antimicrobial, antifungal, anti-inflammatory, and insect repellent properties. Some experiments were done on tea tree oil to determine its insect repellent properties and the suitable concentration that can be used to make sure its repelling effect is optimum. The purpose of this determination is to avoid its harmful effect on humans because it can be toxic if it is used at high concentration. The results showed that tea tree oil repelled Tribolium castaneum. Furthermore, the toxicity assays also gave positive result where the tea tree oil has toxic properties against Solenopsis invicta. The lethal dose (LD) of tea tree oil to kill 50% of a group of S. invicta is 23.52 μL/mL. This LD50 is determined by using the arithmetic method of Karber. Broadly, the results showed that M. alternifolia has insect repellent properties and shows toxicity against certain insects.

New-onset pancytopenia is a common diagnostic challenge. Pancytopenia is an indication for bone marrow examination. The present study has been carried out to determine the frequencies of various etiologies of pancytopenia based on bone marrow morphology in a defined geographical location. All cases of new-onset pancytopenia, diagnosed on peripheral smear and seen over a four-year period from January 2012 to December 2015 in the department of pathology, were analysed. Patients lacking representative bone marrow in the aspirate or receiving chemotherapy were excluded. Out of 69 cases, 29 were males and 40 were females. Most of the patients were in the age group of 19-60 years (52.2%). Nineteen (26.1%) of them were less than 18 years old. The three major causes of pancytopenia were: megaloblastic anemia (hypercellular marrow with megaloblastic erythropoiesis) in 25 (36.2%) cases, hypercellular marrow with dimorphic erythropoiesis in 13 (18.8%) cases, and haematological malignancies in 12 (17.4%) cases of the study. Bone marrow examination along with laboratory evaluation helps to establish specific diagnosis in cases of new-onset pancytopenia.

The present study was conducted to evaluate the toxic potential of tartrazine, a food color, in different tissues in adult rat: blood, liver, kidneys, and spleen. Tartrazine was administered orally at a dose of 300 mg/kg of body weight to adult male Wistar rats during a period of 30 days. Tartrazine treatment led to an increase in platelets count, a reduction in peripheral lymphocytes and in spleen T CD8-lymphocytes. Furthermore, tartrazine increased the activities of hepatocellular enzymes and promoted changes in kidney biomarkers. In order to explore the possible mechanism involved, oxidative-stress assessment was performed. Results identified critical oxidative alterations in all tested organs, as shown by the promotion of lipid peroxidation and the modification of endogenous antioxidant-defense enzymes. Thus, tartrazine is able to induce in adult rats’ hematotoxicity, immunotoxicity, and liver and kidney injuries by changing the whole balance between oxidants and antioxidants.
