Trichomoniasis, one of the most common non-viral sexually transmitted infections worldwide, is caused by the parasite Trichomonas vaginalis. The pathogen colonizes the human urogenital tract, and the infection is associated with complications such as adverse pregnancy outcomes, cervical cancer, and an increase in HIV transmission. The mechanisms of pathogenicity are multifactorial, and controlling immune responses is essential for infection maintenance. Extracellular purine nucleotides are released by cells in physiological and pathological conditions, and they are hydrolyzed by enzymes called ecto-nucleotidases. The cellular effects of nucleotides and nucleosides occur via binding to purinoceptors, or through the uptake by nucleoside transporters. Altogether, enzymes, receptors and transporters constitute the purinergic signaling, a cellular network that regulates several effects in practically all systems including mammals, helminths, protozoa, bacteria, and fungi. In this context, this review updates the data on purinergic signaling involved in T. vaginalis biology and interaction with host cells, focusing on the characterization of ecto-nucleotidases and on purine salvage pathways. The implications of the final products, the nucleosides adenosine and guanosine, for human neutrophil response and vaginal epithelial cell damage reveal the purinergic signaling as a potential new mechanism for alternative drug targets.

There has been growing interest in the development of highly potent and selective protein tyrosine phosphatase (PTP1B) inhibitors for the past 2-3 decades. Though most PTPs share a common active site motif, the interest in selective inhibitors, particularly against PTP1B is increasing to discover new chemical entities as antidiabetic agents. AZD-9574 In the current paradigm to find potent and selective PTP1B inhibitors, which is currently considered as one of the best validated biological targets for non-insulin-dependent diabetic and obese individuals, resistance to insulin due to decreased sensitivity of the insulin receptor is a pathological factor and is also genetically linked, causing type II diabetes.

Insulin receptor sensitization is performed by a signal transduction mechanism via a selective protein tyrosine phosphatase (PTP1B). After the interaction of insulin with its receptor, autophosphorylation of the intracellular part of the receptor takes place, turning it into an active kinase (sensitization). Pds and the screened inhibitors could be used as a template for the further design of potent congeners.

The co-crystallized ligands and the screened inhibitors could be used as a template for the further design of potent congeners.

The present work aimed to develop MT loaded solid Nano dispersion by improving its solubility, half-life and bioavailability in biological system thereby this formulation may be afforded economically.

Small cell lung carcinoma is a type of malignant tumor characterized by uncontrolled cell growth at lung tissues. The potent anti-cancer drug methotrexate (MT) chosen for the present work is poorly soluble in water (BCS type IV class) with short half-life and hepatotoxic effect.

With the concept of polymeric surfactant to improve the solubility along with wettability of drugs, the present work has been hypothesized to improve its solubility using polyvinyl pyrollidone (PVP K30) polymer and α- tocopheryl polyethylene glycol 1000 succinate (TPGS) surfactant, thereby the bioavailability is expected to get enhanced. By varying the PVP K30 and TPGS ratios different formulations were developed using emulsification process.

The developed MT loaded solid nanodispersion was further characterized for its particle n may have anticancer potential for SCLC treatment.

This proof of study indicates that the developed formulation may have anticancer potential for SCLC treatment.Gastric cancer (GC) is found as the second leading cause of cancer associated deaths in the world which is usually detected in the advanced stages. It has been showed that surgery is major therapeutic approach in the treatment subjects with GC. Hence, early and fast diagnosis of this malignancy is very important issue for good subject outcomes. Noninvasive diagnostic platforms including evolutionary endoscopy and positron emission tomography (PET) are employed as diagnosis for subjects with GC. Along to imaging techniques, utilization of biomarkers has been emerged as new diagnosis options in early and fast detection of GC. Multiple lines evidence revealed, a variety of biomarkers including microRNAs, exosomes, circulating tumor cells, circular RNAs, cell free DNAs, and various proteins could be used as diagnostic biomarkers in patients with GC. Taken together, these findings suggested that joint application of imaging techniques and different biomarkers, could be introduced as new detection approaches in the treatment and screening response to therapy in the subjects with GC. Herein, we summarized various imaging techniques and biomarkers as powerful tools in the detection of GC.Premature ovarian failure (POF) refers to ovarian dysfunction in women under 40 years old. It is characterized by low estrogen, high gonadotropin, amenorrhea, and infertility, which seriously affect women's physical and mental health of women. The pathogenic factors of POF include iatrogenic factors, autoimmune factors, genetic factors, oxidative stress, infection, thyroid dysfunction, and adrenal diseases. Chemotherapy is a common cause of POF and is attracting increasing attention. With the development of modern medicine and advances in understanding cancer, women's cancer survival rates have significantly increased. Currently, the main treatment options for POF are hormone supplement and in vitro activation (IVA), but there is still no specific treatment for POF. Stem cells, known as undifferentiated cells of multicellular organisms, exhibit characteristics of self-renewal, directional differentiation into different cells, and low immunogenicity. Thus, they have potential in regenerative medicine and provide a promising direction for POF treatment. In this review, we summarize the latest research progress of various stem cells in chemotherapy-induced POF models to provide a theoretical basis for further research and treatment.
