OBJECTIVE: To evaluate the histopathological effects of smoking before, during and after pregnancy on the intervertebral disc structure of the newborns in an experimental rat model. METHODS: Seven adult female Wistar Albino rats were randomly allocated into 7 groups. Nicotine (2 mg/kg/day) was intraperitoneally introduced to these rats in 6 groups before, during and after pregnancy, while the rat in the control group received isotonic saline intraperitoneally. Fourteen newborns delivered by each rat were sacrificed at the end of 9 weeks after being breastfed for 3 weeks after birth...

REVIEW
TingTing Hong, Robin M Shaw
Unique to striated muscle cells, transverse tubules (t-tubules) are membrane organelles that consist of sarcolemma penetrating into the myocyte interior, forming a highly branched and interconnected network. Mature t-tubule networks are found in mammalian ventricular cardiomyocytes, with the transverse components of t-tubules occurring near sarcomeric z-discs. Cardiac t-tubules contain membrane microdomains enriched with ion channels and signaling molecules. The microdomains serve as key signaling hubs in regulation of cardiomyocyte function...

The primary purpose of this research was to develop and evaluate the efficacy and feasibility of a brief, cost-effective family-focused intervention to promote adaptive coping and quality of life throughout a parent's bone marrow transplantation (BMT). Targeted outcomes were cohesion, decreased use of avoidance coping, open communication and effective management of emotional distress. Participants included an intervention group of 31 families and 29 families in a control group who received usual care. Each family included the BMT recipient, a partner/caregiver and children 10-18 years old...

OBJECTIVE: To investigate the interobserver and test-retest reproducibility of T1ρ and T2 measurements of lumbar intervertebral discs using 3T magnetic resonance imaging (MRI). MATERIALS AND METHODS: This study included a total of 51 volunteers (female, 26; male, 25; mean age, 54 ± 16.3 years) who underwent lumbar spine MRI with a 3.0 T scanner. Amongst these subjects, 40 underwent repeat T1ρ and T2 measurement acquisitions with identical image protocol. Two observers independently performed the region of interest measurements in the nuclei pulposi of the discs from L1-2 through L5-S1 levels...

Z-discs are organizing centers that establish and maintain myofibril structure and function. Important Z-disc proteins are α-actinin, which cross-links actin thin filaments at the Z-disc and Zasp PDZ domain proteins, which directly interact with α-actinin. Here we investigate the biochemical and genetic nature of this interaction in more detail. Zasp52 is the major Drosophila Zasp PDZ domain protein, and is required for myofibril assembly and maintenance. We show by in vitro biochemistry that the PDZ domain plus a C-terminal extension is the only area of Zasp52 involved in the interaction with α-actinin...

Zoanthus kuroshio is a colorful zoanthid with a fluorescent pink oral disc and brown tentacles, which dominates certain parts of the Taiwanese and Japanese coasts. This sea anemone is a rich source of biologically active alkaloids. In the current investigation, two novel halogenated zoanthamines [5α-iodozoanthenamine (1) and 11β-chloro-11-deoxykuroshine A (2)], along with four new zoanthamines [18-epi-kuroshine A (3), 7α-hydroxykuroshine E (4), 5α-methoxykuroshine E (5), and 18-epi-kuroshine E (6)], and six known compounds were isolated from Z...

Previously, we reported that (E)-8-acetoxy-2-[2-(3,4-diacetoxyphenyl)ethenyl]-quinazoline (8-ADEQ), a synthetic analogue of resveratrol had anti-inflammatory and G2/M cell cycle arrest activities, but the underlying molecular mechanism of cytotoxic effects of this compound was not determined. In this study, 8-ADEQ displayed potent cytotoxicity and triggered apoptosis in HL-60 cells as evidenced by DNA fragmentation, DNA ladder formation, and the externalization of Annexin V-targeted phosphatidylserine residues in HL-60 cells...

Kindlin-2, a member of the Kindlin family focal adhesion proteins, plays an important role in cardiac development. It is known that defects in the Z-disc proteins lead to hypertrophic cardiomyopathy (HCM) or dilated cardiomyopathy (DCM). Our previous investigation showed that Kindlin-2 is mainly localized at the Z-disc and depletion of Kindlin-2 disrupts the structure of the Z-Disc. Here, we reported that depletion of Kindlin-2 leads to the disordered myocardial fibers, fractured and vacuolar degeneration in myocardial fibers...

The aim of this study was to identify the possible correlation between polymorphisms in matrix metalloproteinase (MMP)-1 and MMP-3 and their corresponding protein levels in disc tissues obtained from patients with lumbar disc herniation (LDH) using biochemical and immunohistochemical analyses. Blood and disc samples were obtained from 100 patients with LDH who underwent a lumbar microdiscectomy. Based on the radiological degeneration, the patients were diagnosed with grade 2, 3, or 4 LDH. MMP-1 -1607 1G/2G and MMP-3 -1171 5A/6A were analyzed by real-time polymerase chain reaction...

OBJECTIVE: Cervical disc arthroplasty (CDA) has been designed as a substitute for anterior cervical discectomy and fusion (ACDF) in the treatment of symptomatic cervical disc disease (CDD). Several researchers have compared CDA with ACDF for the treatment of symptomatic CDD; however, the findings of these studies are inconclusive. Using recently published evidence, this meta-analysis was conducted to further verify the benefits and harms of using CDA for treatment of symptomatic CDD. METHODS: Relevant trials were identified by searching the PubMed, EMBASE, and Cochrane Library databases...

Symbioses between ciliate hosts and prokaryote or unicellular eukaryote symbionts are widespread. Here, we report on a novel ciliate species within the genus Zoothamnium Bory de St. Vincent, 1824, isolated from shallow-water sunken wood in the North Adriatic Sea (Mediterranean Sea), proposed as Zoothamnium ignavum sp. nov. We found this ciliate species to be associated with a novel genus of bacteria, here proposed as "Candidatus Navis piranensis" gen. nov., sp. nov. The descriptions of host and symbiont species are based on morphological and ultrastructural studies, the SSU rRNA sequences, and in situ hybridization with symbiont-specific probes...

Distal myopathies and myofibrillar myopathies are both rare subcategories of muscle diseases. Myofibrillar myopathies are genetically heterogeneous group of diseases characterized by distinctive histopathology of abnormal protein aggregations and myofibrillar disintegration. All genes causing myofibrillar myopathy encode proteins that either reside in or associate with the Z-disc. Distal myopathies are also genetically heterogeneous muscular dystrophies in which muscle weakness presents distally in the feet and/or hands...

BACKGROUND: Certain behavior types can drive the emergence of an unsafe act at the workplace which may be reflected by workers' perceptions toward safety climate. OBJECTIVE: The purpose of this study was to explore the relationship between workers' safety climate perceptions (NOSACQ-50 questionnaire) and their behavior types (based on DISC personality traits: Dominance, Influence, Steadiness, and Conscientiousness). METHODS: NOSACQ-50 and DISC assessment questionnaires were distributed on employees of four different companies (N = 755) working at hazardous workplaces in different occupational fields: fertilizer, coal mining, and oil & gas...
