Craniofacial deformities with multifactorial etiologies, such as cleft palate and facial dysmorphism, represent some of the most frequent congenital birth defects seen in humans. Their pathogeneses are often related to cranial neural crest (CNC) cells. During CNC cell migration, changes in cell shape and formation, as well as maintenance of subcellular structures, such as filopodia and lamellipodia, are dependent on the complex functions of Rho family small GTPases, which are regulators of actin cytoskeletal organization...

Neuronal activity induces intracellular Ca(2+) increase, which triggers activation of a series of Ca(2+) -dependent signalling cascades. Among these, the multifunctional Ca(2+) / calmodulin-dependent protein kinases (CaMKs, or calmodulin kinases) play key roles in neuronal transmission, synaptic plasticity, circuit development and cognition. The most investigated CaMKs for these roles in neuronal functions are CaMKI, CaMKII, CaMKIV and we will shed light on these neuronal CaMKs' functions in this review. Catalytically active members of CaMKs currently are CaMKI, CaMKII, CaMKIV and CaMKK...

Tooth agenesis is described as the absence of one or more teeth. It is caused by a failure in tooth development and is one of the most common human developmental anomalies. We herein report genomic analyses of selective mandibular incisor agenesis (SMIA) using exome sequencing. Two Japanese families with SMIA were subjected to exome sequencing, and family with sequence similarity 65 member A (FAM65), nuclear factor of activated T-cells 3 (NFATC3) and cadherin-related 23 gene (CDH23) were detected. In the follow-up study, 51 Japanese and 32 Korean sporadic patients with SMIA were subjected to exome analyses, and 18 reported variants in PAX9, AXIN2, EDA, EDAR, WNT10A, BMP2 and GREM2 and 27 variants of FAM65, NFATC3 and CDH23 were found in 38 patients...

A strategy for the preservation of intrarenal vasculature conditions remains obscure in middle-aged and older individuals without the renal disease. In the present study, we sought to identify whether the maintenance of muscular strength is an effective method of preserving the intrarenal vasculature condition of middle-aged and older individuals. Therefore, we applied a cross-sectional approach for investigating the relationship between muscular strength and the condition of the intrarenal vasculature. In 169 middle-aged and older individuals without renal disease, handgrip strength (HGS) and the renal resistive index (RRI) were measured as the parameters of muscular strength and intrarenal vascular resistance, respectively...

The purpose of this study was to examine the effect of habitual exercise on urinary liver-type fatty acid-binding protein (L-FABP), which can reflect the degree of various stresses on renal proximal tubule related to the progression of renal disease, in middle-aged and older adults. Cross-sectional and interventional approaches were used to comprehensively achieve this purpose. In the cross-sectional study, we investigated the relationship between physical activity levels and urinary L-FABP levels in 130 middle-aged and older adults...

Sustainability has become a key issue in managing natural resources together with growing concerns for capitalism, environmental and resource problems. We hypothesize that the ongoing modernization of competitive societies, which we refer to as "capitalism," affects human nature for utilizing common pool resources, thus compromising sustainability. To test this hypothesis, we design and implement a set of dynamic common pool resource games and experiments in the following two types of Nepalese areas: (i) rural (non-capitalistic) and (ii) urban (capitalistic) areas...

Animals choose reproductive partners based on their sexual preferences which are established at a certain time point before, during, or after sexual maturation. The preferences are often divergent within a species, which suppresses gene flow between populations and may promote speciation. There are two strains of medaka (Oryzias latipes) that differ by a single transgene and mate assortatively depending on skin color. Here, we demonstrate that symmetrically biased (mutually exclusive) sexual preferences are (1) gradually established during growth depending on skin color and the color of surrounding fish, (2) strong enough to minimize gene flow between the strains at a population level, and (3) inflexibly retained after sexual maturation, even after weeks of daily mating with partners of the other strain...

BACKGROUND: The underlying mechanism linking the decline in exercise capacity with renal dysfunction remains unclear. Urinary liver-type fatty acid-binding protein (L-FABP) levels reflect the degree of peritubular capillary blood flow, an important factor for renal dysfunction with aging. The aim of this study was to examine the relationship between exercise capacity and urinary L-FABP levels. METHODS: This was a cross-sectional study of 187 middle-aged and older individuals (aged 50-83 years) without chronic kidney disease (CKD)...

The synthesis of alkylated pyrimidines was achieved via benzophenone-mediated photoinduced coupling between saturated heterocycles and sulfonylpyrimidines. The pyrimidine ring was selectively introduced at the nonacidic C(sp(3))-H bond proximal to heteroatoms including oxygen, nitrogen, and sulfur. This is a coupling reaction mediated solely by photoexcited benzophenone, an organic molecule, without the aid of any metallic catalysts or reagents.

OBJECTIVES: Aerobic glycolysis, the main pathway of energy production in tumors (Warburg effect) allows detection of tumors by positron emission tomography (PET) using 18F-fluoro-2-deoxy-D-glucose (18F-FDG). Since ionizing radiation (IR) is reported to switch aerobic glycolysis to mitochondrial oxidative phosphorylation, radiotherapeutic efficacy was monitored by the activity of mitochondrial complex I (MC-I), using a new PET probe 18F-BCPP-EF, 18F-2-tert-butyl-4-chloro-5-{6-[2-(2-fluoro-ethoxy)-ethoxy] -pyridine-3-ylmethoxy}-2H-pyridazin-3-one, compared with 18F-FDG uptake and the apoptosis index...

BACKGROUND: When performing arthroscopic ankle arthrodesis for end-stage ankle arthritis, internal fixation is performed using bone screws after appropriate preparation. However, optimal characteristics of bone screws have not been examined in terms of pressure force. Objective comparisons of bone-screw performance may provide information on procedures for arthroscopic ankle arthrodesis. The study objectives were to determine whether it was possible to measure compressive force changes using the newly developed device and to infer all screw characteristics from measurement results when used in actual surgeries...

Nephronectin (Npnt), an extracellular matrix protein, is considered to play critical roles as an adhesion molecule in the development and functions of various organs and tissues, such as the kidneys and bone. In the present study, we found that Wnt3a strongly enhanced Npnt mRNA expression in osteoblast-like MC3T3-E1 cells, while it also induced an increase in Npnt gene expression in both time- and dose-dependent manners via the Wnt/β-catenin signaling pathway. These results suggest novel mechanisms for Wnt3a-induced osteoblast proliferation and cell survival via Npnt gene expression...

Osteoarthritis is a degenerative joint disease caused by excessive death of chondrocytes and loss of the extracellular matrix (ECM) in articular cartilage. We previously reported that reactive oxygen species (ROS) generated by the NADPH oxidase (NOX) isoform NOX-2 are involved in chondrocyte death induced by interleukin-1β (IL-1β). In this study, we investigate the role of NOX-2 in the production and degradation of ECM by chondrocytes. Although IL-1β lowered the mRNA expression of type II collagen (Col2a1) and aggrecan (Acan) in mouse chondrocyte-like ATDC5 cells, RNA silencing of Nox2 did not change the mRNA expression of these major components of the ECM of cartilage...

The catalytic introduction of an allyl group at nonacidic C(sp(3))-H bonds was achieved under photoirradiation, in which 1,2-bis(phenylsulfonyl)-2-propene acts as an allyl source and 5,7,12,14-pentacenetetrone (PT) works as a C-H bond-cleaving catalyst. A variety of substances, including alkanes, carbamates, ethers, sulfides, and alcohols, were chemoselectively allylated in a single step under neutral conditions. The present transformation is catalyzed solely by an organic molecule, PT, and proceeds smoothly even under visible light irradiation (425 nm) in the case of alkanes as a starting substance...

Liposome-encapsulated hemoglobin (LEH) with high (h-LEH, P50 O2  = 10 mm Hg) or low O2 affinity (l-LEH, P50 O2  = 40 mm Hg) may improve O2 delivery to sensitize tumor tissues for radiotherapy. A total of 10 mL/kg of h-LEH, l-LEH, red blood cells (RBCs), or saline was infused in mice transplanted with murine colon carcinoma with near-infrared spectroscopy (NIRS) detectors set at the tumor (right leg) and intact muscle (left leg). NIRS recorded changes in the amount of oxyhemoglobin (oxyHb), deoxyhemoglobin (deoxyHb), and their sum (tHb) with the animals spontaneously breathing room air (10 min), pure O2 (5 min), and then back to room air...
