Engineered Extracellular Vesicles In article number 2204031, Jing Zhao, Guodong Yang, Angang and co-workers develop an extracellular vesicle-based GSDMD-N mRNA delivery system (EVTx), in which is encapsulated inside the vesicle, HER2 antibody displayed on surface, sonosensitizer Ce6 incorporated into membrane. When endocytosed by HER2+ cancer cells, EVTx efficiently induces pyroptosis thus enha...
Background and Objectives: Caffeine decreases the testis volume and the number of spermatogenic cells in seminiferous tubules of rat testis. Therefore, the aim of this study was to assess the impact of caffeine exposure during pregnancy and lactation on seminal vesicle and epididymis in rat offspring. Materials and Methods: In this experimental study, 21female pregnant rats were divided into ...
NO is a free radical that regulates a variety of developmental modulation processes. NO is synthesized by NOS and it acts as a neurotransmitter, neuromodulator or second messenger molecule in the central nervous system. Since NO production may be different before or after birth, the expression of neuronal nitric oxide synthase was examined and analysized during the development of rat optic ...
conclusions the results showed that the extracted omvs were conformationally stable, and there were no pyrogenic determinants in omv. also the results showed that the omv elicited high level of specific antibodies against n. meningitidis serogroup a. these results indicate that the omv obtained here, can be used as a meningococcal vaccine after further investigation. materials and methods omvs ...
results the main pathological finding observed in the prostrate and seminal vesicle glands, using light microscope, revealed congestion in the connective tissue and vacuolization in the secretory units of epithelial cells and epithelium rupture at 50 and 100 µg/kg doses of bpa. ultrastructure study showed vacuolization of mitochondria, condensation of nuclei and disappearance of nucleus in the ...
A microneedle puncture of the fibroblast or sea urchin egg surface rapidly evokes a localized exocytotic reaction that may be required for the rapid resealing that follows this breach in plasma membrane integrity (Steinhardt, R.A,. G. Bi, and J.M. Alderton. 1994. Science (Wash. DC). 263:390–393). How this exocytotic reaction facilitates the resealing process is unknown. We found that starfish o...
Background and purpose: Diabetes causes adverse effects on the activity of reproductive system, including impaired spermatogenesis, decreased sperm count, testosterone serum, seminal fluid volume, and loss of sexual desire. The aim of this study was to evaluate the effect of E.cyparissias extract on tissue changes of prostate and vesicle seminal in diabetic rats. Materials and methods: Thirty ...
Abstract The synthesis of polymer-vesicle latex particles by using extruded vesicles dimethyldioctadecyl ammonium bromide (DODAB) via an atom transfer radical polymerization–based approach is reported. Cryo-TEM characterization revealed the growth polymer from one side vesicle, and final morphology resulting was affected monomer feed composition. Protrusions or nanocapsules were synthesized whe...
Background: Superficial mucocele presents as small, clear vesicle on noninflamed mucosa. In this study, we report several vesicles on the bucal mucosa of a woman diagnosed as superficial mucocele.Case Presentation: A 48-year old woman presented with multiple vesicles on her labial mucosa, ventral surface of the tongue, floor of the mouth and palate. A mucosal biopsy was taken from the vesicle. ...
