Understanding how episodic memories are formed and retrieved is necessary if we are to treat disorders in which they malfunction. Muscarinic acetylcholine receptors (mAChR) in the hippocampus and cortex underlie memory formation, but there is conflicting evidence regarding their role in memory retrieval. Additionally, there is no consensus on which mAChR subtypes are critical for memory processing. Using pharmacological and genetic approaches, we found that (1) encoding and retrieval of contextual memory requires mAChR in the dorsal hippocampus (DH) and retrosplenial cortex (RSC), (2) memory formation requires hippocampal M3 and cooperative activity of RSC M1 and M3, and (3) memory retrieval is more impaired by inactivation of multiple M1-M4 mAChR in DH or RSC than inactivation of individual receptor subtypes...

Water temperature is an environmental factor of primary importance that influences reproductive function in fish. To understand the molecular and physiological mechanisms underlying the regulation of reproduction by temperature, we examined changes in expression of genes encoding kisspeptin (kiss2), kisspeptin receptor (kiss2r) and three gonadotropin-releasing hormones (gnrh1, gnrh2 and gnrh3) in the brain and genes encoding gonadotropin (GTH) subunits (gpa, fshb and lhb) in the pituitary of grass puffer exposed to a low temperature (14°C), normal temperature (21°C) and high temperature (28°C) for 7 days...

Polarized Raman spectroscopy was applied to evaluate the full set of stress tensor components in the wear-induced residual stress fields on two long-term (>20 y) (monolithic) alumina (Al2O3) femoral head retrievals coupled to polyethylene liners. The tensor-resolved residual stress state stored onto the Al2O3 ceramic head surface was found to retain "memory" of the sliding conditions in vivo and of the wear-induced consumption of the polyethylene counterpart. The evolution of tensor-resolved residual stress motifs in the three-dimensional space was examined, and key features, including exceptionally high shear stresses in one case, were uncovered...

BACKGROUND: Prevalent hemodialysis patients with vascular access consisting of a central venous catheter (CVC) are continuously increasing over the years. Improvement in evolution and CVC placement procedures represents therefore an essential tool to enhance performance and reduce intraoperative and long-term CVC complications. Internal jugular vein (IJV) catheterization techniques are different according to ultrasound probe position in relation to vein axis and to needle direction in relation to ultrasound beam...

Limbal stem cell deficiency (LSCD) is a state of malfunction or loss of limbal epithelial stem cells, after which the corneal epithelium is replaced with conjunctiva. Patients suffer from recurrent corneal defects, pain, inflammation, and loss of vision. Previously, a murine model of LSCD was described and compared to two other models. The goal was to produce a consistent mouse model of LSCD that both mimics the phenotype in humans and lasts long enough to make it possible to study the disease pathophysiology and to evaluate new treatments...

Early detection of cancer is the key to improving survival. Since most clinically used serum cancer biomarkers are either glycoproteins or glycan structures that can be recognized by specific monoclonal antibodies, developing glycan structure-based biomarkers from human serum/plasma glycoproteins through mass spectrometry (MS) analysis are active research field during the past decades. Numerous studies have shown that changes in serum/plasma glycan structures occur during cancer initiation, progression, and treatment...

Hexavalent chromium could result in cell malfunctions. Intracellular Ca(2+) ([Ca(2+)]i) content and VDAC1 expression are both important features related to cell survial. This study aimed to explore the mechanism of cell injury induced by Cr(VI) and tentatively offer clues to repairing this cell damage using [Ca(2+)]i and VDAC1. L-02 hepatocytes were treated with Cr(VI)/BAPTA, and the levels of [Ca(2+)]i and cell injury associated with Cr(VI) were determined in addition to the effect of BAPTA. The expression of VDAC1 in Cr(VI)-induced cells was evaluated...

Due to its high dimensionality and high noise levels, analysis of a large brain functional network may not be powerful and easy to interpret; instead, decomposition of a large network into smaller subcomponents called modules may be more promising as suggested by some empirical evidence. For example, alteration of brain modularity is observed in patients suffering from various types of brain malfunctions. Although several methods exist for estimating brain functional networks, such as the sample correlation matrix or graphical lasso for a sparse precision matrix, it is still difficult to extract modules from such network estimates...

Acute respiratory failure (ARF) is defined as a sudden malfunction in the ability of respiratory system to maintain adequate gas exchange. Acute hypercapnic respiratory failure develops as a result of ventilation deficiency and it is defined as an increase of PaCO2 above 45 mmHg. Myasthenia Gravis (MG) is a sporadically developing auto-immune deficiency where the neuro-muscular transmission is affected and it is one of the important reasons for neurologically-induced respiratory distress. Here, we report a case of a 75-year-old male patient previously undiagnosed MG, who presented with ARF...

BACKGROUND: Analog blanking periods (BP) that hold down the display of electrograms (EGM) in cardiac rhythm devices have received much less attention than the well-known digital blanking periods which do not influence the EGM display. In Biotronik devices, when a paced event initiates an analog BP in one chamber [right atrium (RA), right ventricle (RV) or left ventricle (LV)], an identical cross-chamber analog BP starts in the other 2 chambers. METHODOLOGY: All clinical observations were recorded from patients with Biotronik devices...

Aldehyde reductase (Akr1a) is involved in the synthesis of ascorbic acid (AsA) which may play a role in social behavior. In the current study, we performed analyses on Akr1a-deficient (Akr1a(-/-)) mice that synthesize about 10% as much AsA as wild-type mice from the viewpoint of intermale aggression. The use of the resident-intruder test revealed that the Akr1a(-/-) mice exhibited more aggressive phenotypes than wild-type control mice. Unexpectedly, however, the oral administration of additional AsA failed to reduce the aggressive behavior of Akr1a(-/-) mice, suggesting that the heightened aggression was independent of AsA biosynthesis...

BACKGROUND: The control of energy metabolism is fundamental for cell growth and function and anomalies in it are implicated in complex diseases and ageing. Metabolism in yeast cells can be manipulated by supplying different carbon sources: yeast grown on glucose rapidly proliferates by fermentation, analogous to tumour cells growing by aerobic glycolysis, whereas on non-fermentable carbon sources metabolism shifts towards respiration. RESULTS: We screened deletion libraries of fission yeast to identify over 200 genes required for respiratory growth...
