Folliculogenesis is a compound process that involves both ovarian follicle growth and oocyte development, which is tightly attached to the follicular wall. During this process, cells that form the follicle structure undergo substantial morphological and molecular modifications that finally lead to differentiation and specialization of ovarian follicular cells. The differentiation of ovarian cells encompasses formation of follicle, which is composed of theca (TCs), mural granulosa (GCs), and cumulus cells (CCs)...

Testicular compartment syndrome (TCS) refers to the impairment of microcirculation in the testicle due to either increased venous resistance or extraluminal compression, which leads to hypoxia. TCS releases oxidants through hypoxia and ischemia/reperfusion injury (IRI). The pathophysiology, etiology, evaluation, and management of TCS are reviewed. Based on the properties of TCS, specific causes, e.g., varicocele, hydrocele, orchitis, cryptorchidism, and scrotal hernia, are suggested and categorized. The oxidant-induced stress from TCS may explain the correlations between these causes and infertility...

BACKGROUND: School-based treatment and counseling services (TCSs) can integrate mind-body techniques (MBTs) to improve children's health, wellness, and academic performance. We aimed to describe the effect of school-based TCS on MBT-use among students experiencing difficulties with concentration, emotions, behaviors, and getting along (DCEBG). METHODS: National Health Interview Survey data were utilized (N2007  = 1225; N2012  = 1835). Logistic regression examined associations between TCS-type and MBT-use, while propensity score matching controlled for confounders in the prematch sample...

Blood mononuclear cells consist of T cells and monocyte derived cells. Beside immunity, the blood mononuclear cells belong to the complex tissue control system (TCS), where they exhibit morphostatic function by stimulating proliferation of tissue stem cells followed by cellular differentiation, that is stopped after attaining the proper functional stage, which differs among various tissue types. Therefore, the term immune and morphostatic system (IMS) should be implied. The TCS-mediated morphostasis also consists of vascular pericytes controlled by autonomic innervation, which is regulating the quantity of distinct tissues in vivo...

Bacteria use two-component systems (TCSs) to react appropriately to environmental stimuli. Typical TCSs comprise a sensor histidine kinase that acts as a receptor coupled to a partner response regulator that coordinates changes in bacterial behavior, often through its activity as a transcriptional regulator. TCS interactions are typically confined to cognate pairs of histidine kinases and response regulators. We describe two distinct TCSs in uropathogenic Escherichia coli (UPEC) that interact to mediate a response to ferric iron...

Triclosan (TCS) exists ubiquitously in the environment. Several in vitro and in vivo studies have demonstrated that TCS exerts endocrine disruptive effects on reproduction, but data from human populations are limited and conflicting. The objective of our study was to investigate whether high urinary TCS concentration is adversely associated with early reproductive outcomes in women undergoing in vitro fertilization-embryo transfer (IVF-ET). This prospective cohort study was conducted from September 2015 to June 2016, including 156 infertile women undergoing their first IVF-ET cycle...

QseB is a response regulator of the QseBC two-component system (TCS) which is associated with quorum sensing and functions as a global regulator of flagella, biofilm formation, and virulence. The function of QseB and its interaction with QseC has been the subject of study in some organisms, however, little work was done in Salmonella enterica serovar Typhi (S. Typhi). The objective of this study was to investigate the effect of QseB on biofilm formation and virulence in S. Typhi. It showed that the biofilm formation ability of qseC mutant was limited as compared to the wild type strain...

Optimal histopathological analysis of biopsies from metastases of neuroendocrine tumor (NET) of the lung requires more than morphology only. Additional parameters such as Ki-67 labeling index are required for adequate diagnosis, but few studies have compared reproducibility of different counting protocols and modalities of reporting on biopsies of lung NET. We compared the results of four different manual counting techniques to establish Ki-67 LI. On 47 paired biopsies and surgical specimens from 22 typical carcinoids (TCs), 14 atypical carcinoids (ACs), six large cell neuroendocrine carcinomas (LCNECs), and five small cell carcinomas (SCCs) immunohistochemical staining of Ki-67 antigen was performed...

INTRODUCTION: Abdominal based breast reconstruction exists in a continuum from pedicled transverse rectus abdominis myocutaneous (TRAM) flap to deep inferior epigastric perforator (DIEP) free flap. DIEP flap has the advantage of complete rectus abdominis sparing during harvest, thus decreasing donor site morbidity. Aim of this study is to determine whether the surgical advantages of the DIEP flap impact postoperative outcomes versus the free TRAM flap (fTRAM). METHODS: We reviewed the Nationwide Inpatient Sample database (2010-2011) for all cases of DIEP and fTRAM breast reconstruction...

Orexins are neuropeptides that are localized to neurons in the lateral and dorsal hypothalamus but its receptors are distributed to many different regions of the central nervous system. Orexins are implicated in a variety of physiological functions including sleep regulation, energy homeostats, and stress reactions. Furthermore, orexins administered exogenously have been shown to have analgesic effects in animal models. A type of intractable pain in patients is pain due to chemotherapy-induced peripheral neuropathy (CIPN)...

Glioblastoma (GBM) is the most common and malignant type of primary brain tumor and associated with a devastating prognosis. Signal transducer and activator of transcription number 3 (STAT3) is an important pathogenic factor in GBM and can be specifically inhibited with Stattic. Metformin inhibits GBM cell proliferation and migration. Evidence from other tumor models suggests that metformin inhibits STAT3, but there is no specific data on brain tumor initiating cells (BTICs).We explored proliferation and migration of 7 BTICs and their differentiated counterparts (TCs) after treatment with Stattic, metformin or the combination thereof...

: Understanding how each of the many interneuron subtypes affects brain network activity is critical. In the mouse olfactory system, mitral cells (MCs) and tufted cells (TCs) comprise parallel pathways of olfactory bulb output that are thought to play distinct functional roles in odor coding. Here, in acute mouse olfactory bulb slices, we test how the two major classes of olfactory bulb interneurons differentially contribute to differences in MC vs. TC response properties. We show that while TCs respond to olfactory sensory neuron (OSN) stimulation with short latencies, regardless of stimulation intensity, MC latencies negatively correlate with stimulation intensity...

Infertility is actually widespread pathological condition, which affected one in every four couples in developing countries. Approximately one third of all cases are connected with tubal factor infertility, o en accompanies by endometriosis, acute salpingitis, urogenital infections etc. The newly identified telocytes (TCs) have multiple potential bio-functions and might participate in the fertility problems. They influence on structural and functional integrity of oviduct tissue. Despite recent discovery, TCs involvement in the majority of physiological and pathological processes is still unclear and require significant increasing of deep observations and data analysis...

A growing body of evidence suggests that amending soil with biosolids can be an integral component of sustainable agriculture. Despite strong evidence supporting its beneficial use in agriculture, there are concerns that chemicals, such as pharmaceuticals and personal care products (PPCPs), could present a risk to terrestrial ecosystems and human health. Triclosan (TCS) is one of the most commonly detected compounds in biosolids. To date, laboratory studies indicate that TCS likely poses a de minimis risk to field crops; however, these studies were either conducted under unrealistic exposure conditions or only assessed one or two formulations of biosolids...

Concern over tetracyclines (TCs) complexation with metals in the environment is growing as a new class of emerging contaminants. TCs exist as a different net charged species depending on their dissociation constants, pH and the surrounding environment. One of the key concerns about TCs is its strong tendency to interact with various metal ions and form metal complexes. Moreover, co-existence of TCs and metals in the environment and their interactions has shown increased antibiotic resistance. Despite extensive research on TCs complexation, investigations on their antibiotic efficiency and pharmacological profile in bacteria have been limited...
