Pesticide exposure promotes disease activity by decreasing lymphoproliferative activity and increasing IL-4 production in systemic sclerosis patients.

Background: One of the common findings in systemic sclerosis (SSc) patients has been long-term exposure to environmental toxins such as pesticides. However, the data available shows an equivocal association between pesticide exposure and autoimmunity in SSc.

Methods: We investigated the levels of organochlorine pesticides (OCPs) in blood of 20 SSc patients and 17 healthy controls, and also studied their effect on T lymphocytes and their functional responses.

Organochlorine pesticides disrupt T helper cell regulation and reduce IL-2 and IFN-γ favoring infection and production of autoantibodies among pemphigus patients.

The list of environmental factors that trigger autoimmune diseases in genetically susceptible individuals has grown in the recent years and is far from complete. The possible intervention of the environment in triggering these diseases is ever more perceived by the clinicians. This study investigated the effect of environmental factors like organochlorine pesticides (OCPs) on proportions of different T lymphocyte subsets and their cytokine secretion in-vitro among pemphigus patients, before and after specific immunosuppressive therapy.

Risk Factors of Incident Kidney Stones in Indian Adults: A Hospital-Based Cross-Sectional Study.

Background The diverse manifestations of urolithiasis provide very interesting epidemiological data. This has prompted various studies to look into the etiopathogenesis of renal stones, which is believed to be multifactorial, both exogenous and endogenous. VDR Fok1 is a risk factor for renal stone formation and could cause the formation of renal stones through the mechanism of crystal induction and crystallization in the urine.

Putative interactions between transthyretin and endosulfan II and its relevance in breast cancer.

The unregulated use of organochlorine pesticides (OCPs) has been linked to spread of breast cancer (BC), but the underlying biomolecular interactions are unknown. Using a case-control study, we compared OCP blood levels and protein signatures among BC patients. Five pesticides were found in significantly higher concentrations in breast cancer patients than in healthy controls: p',p' dichloro diphenyl trichloroethane (DDT), p'p' dichloro diphenyl dichloroethane (DDD), endosulfan II, delta-hexachlorocyclohexane (dHCH), and heptachlor epoxide A (HTEA).

Deregulated phenotype of autoreactive Th17 and Treg clone cells in pemphigus vulgaris after in-vitro treatment with desmoglein antigen (Dsg-3).

The loss of balance between regulatory T (Treg) and T helper 17 (Th17) causes loss of tolerance against desmoglein (Dsg)-3 leading to pemphigus vulgaris (PV), an autoimmune bullous skin disorder associated with autoantibodies against Dsg-3. We aimed to elucidate the complex relationship of Th17 and Treg cells, their molecules, and the underlying mechanism in the development of PV disease. Using cytokine secretion assays, Th17 and Treg cells were sorted by FACS Aria-III within Dsg-3-responsive PBMC population and homogeneous T cell clones were generated in-vitro.

The study was designed to evaluate the modulation of mTOR complex 1 (mTORC1) and IL-6 genes following the use of mirror therapy (MT) and pregabalin in complex regional pain syndrome type-1 patients. Two groups of 20 patients: MT group received MT and pregabalin, control therapy group received pregabalin. Neuropathic pain symptom inventory (NPSI), numeric rating scale - pain, modified motor activity log, SF-12 questionnaire for quality of life and IL-6 and mTORC1 expression were evaluated.

Xeno-Estrogenic Pesticides and the Risk of Related Human Cancers.

In recent decades, "environmental xenobiotic-mediated endocrine disruption", especially by xeno-estrogens, has gained a lot of interest from toxicologists and environmental researchers.

Organochlorine pesticides induce epithelial as well as inflammatory mediators following exposure to human ovarian surface epithelial cells: An in vitro study.

Although studies have suggested organochlorine pesticides (OCPs) exposure increased the risk of epithelial ovarian cancer, the mechanisms underlying its potential tumorigenic effects in the human ovary are not well understood. In this study, we investigated the impact of dichlorodiphenyldichloroethylene (DDE), endosulfan, and heptachlor exposure on epithelial cadherin (E-cadherin) and proinflammatory mediators in human ovary surface epithelial (HOSE) cells. We found that DDE, endosulfan, and heptachlor exposure resulted in epithelial differentiation accompanied by upregulation of E-cadherin expression and overexpression of proinflammatory cytokines (TNFα, IL-1β, and IL-6) in HOSE cells.

Graphene quantum dot-porphyrin/phthalocyanine multifunctional hybrid systems: from interfacial dialogue to application.

Engineered well-ordered hybrid nanomaterials are symbolically at a pivotal point, just ahead of the long-anticipated transformation of the human race. Incorporating newer carbon nanomaterials like graphene quantum dots (GQDs) with tetrapyrrolic porphyrins (Pp) and phthalocyanines (Pc) is crucial for achieving exquisite molecular nanoarchitectures that are superior to their individual components. The outcomes of this, particularly in the case of graphene quantum dot-porphyrin/phthalocyanine (GQD-Pp/Pc) hybrids, remain comprehensively unexplored to date.

Exotic Hydrogel Matrix as an Efficient Platform for Sustainable Production of Biomass and Lipid from .

Concerning the climate crisis, energy disaster, and greenhouse effects, microalgae have paved the way for consideration as a biofuel feed material. The advent of polymeric materials with unique architecture at nanoscale, in combination with microalgae, has given direction for the bioeconomic yield of highly valued compounds, essentially lipid. Herein, we discuss the paramount significance of exotic hydrogel matrix (HM) with efficient violet light absorption, far-red emission, CO-adsorbing capability and catalyst-free condition that could increase the photosynthesis activity, alleviating the microalgal growth for the effective augmentation of lipid, protein, and chlorophyll.

Adipose Tissue Levels of DDT as Risk Factor for Obesity and Type 2 Diabetes Mellitus.

Background: Exposure to dichlorodiphenyltrichloroethane (DDT), a potent lipophilic organochlorine pesticide, has long been linked as a risk factor for type 2 diabetes mellitus (T2DM). However, its presence in the adipose tissues of the T2DM subjects has not been explored in the Indian population, where this long-banned pesticide is still in use. The present study was conducted to evaluate the possible association of DDT and its metabolites in obese and non-obese T2DM subjects.
