BACKGROUND: Alcohol use disorders (AUDs) are influenced by complex interactions between the genetics of the individual and their environment. We have previously identified hundreds of polygenic genetic variants between the selectively bred high and low alcohol drinking (HAD and LAD) rat lines. Here we report allele specific expression (ASE) differences, between the HAD2 and LAD2 rat lines. METHODS: The HAD2 and LAD2 rats which have been sequenced were reciprocally crossed to generate 10 litters of F1 progeny...

BACKGROUND Obstructive jaundice is a serious, life-threatening condition that can lead to death as a result of sepsis and multiorgan failure due to bacterial translocation. Treatment should be started as soon as possible after diagnosis. MATERIAL AND METHODS Forty 24-week-old male Sprague Dawley rats, with an average weight of 250 g to 300 g, were included in this study. The rats were randomly placed into five groups, each group consisted of eight rats. The sham group underwent only common bile duct (CBD) dissection and no ligation was performed...

Functional genomics studies in minimal mycoplasma cells enable unobstructed access to some of the most fundamental processes in biology. Conventional transposon bombardment and gene knockout approaches often fail to reveal functions of genes that are essential for viability, where lethality precludes phenotypic characterization. Conditional inactivation of genes is effective for characterizing functions central to cell growth and division, but tools are limited for this purpose in mycoplasmas. Here we demonstrate systems for inducible repression of gene expression based on clustered regularly interspaced short palindromic repeats-mediated interference (CRISPRi) in Mycoplasma pneumoniae and synthetic Mycoplasma mycoides, two organisms with reduced genomes actively used in systems biology studies...

Chronic aortic dissecting aneurysms (TAAD) presenting after acute Stanford Type A or B dissection includes both arch and/or thoracoabdominal aortic aneurysms (TAAA). Approximately 60% of patients who survive surgical treatment of acute Type A aortic dissections will require another aortic procedure. Similarly, more than 70% of patients with chronic Type B aortic dissections will experience false lumen dilation at 5-year follow-up, often requiring intervention. Open or hybrid aortic repairs of complex TAAD involving the arch and the TAAA are very demanding procedures for both patients and clinicians...

Percutaneous transluminal angioplasty and stenting is becoming increasingly the first line treatment for patients with both claudication and critical limb ischaemia instead of surgery, with the aim of returning the patient's quality of life in the former and preventing amputation. Drug eluting technologies have seen a large surge in popularity in recent years, and significant patient benefits have been seen with the use of drug eluting stents and balloons over the use of plain balloon angioplasty. Unfortunately in many patients with arterial disease there is significant vessel wall calcification - this can theoretically be a barrier to drug delivery, and can also be a contributing factor to flow limiting dissection and the subsequent need for bail out stenting...

BACKGROUND: Sentinel node navigation surgery (SNNS) in early gastric cancer (EGC) is technically feasible according to previous literature, however its long-term oncologic safety has not been reported. METHODS: A single-center, single-arm, phase II trial was conducted to determine the oncologic outcomes of laparoscopic sentinel node (SN) biopsy in clinical stage T1N0M0 gastric cancer patients. Cases with positive SNs on intraoperative pathologic examination underwent conventional gastrectomy with radical lymphadenectomy (SN-positive group), whereas those with negative SNs underwent laparoendoscopic-limited gastric resections without further lymph node dissections (SN-negative group)...

BACKGROUND: Prophylactic central compartment neck dissection (pCCND) in addition to total thyroidectomy (TT) includes removal of central compartment lymph nodes in the absence of clinical involvement on preoperative and intraoperative evaluation. The data regarding the influence of pCCND on oncologic outcomes and surgical complication rates is mixed and, therefore, is the focus of this analysis. METHODS: A systematic review of the literature on total thyroidectomy with prophylactic central compartment neck dissection (TT + pCCND) from January 1990 to October 2017 identified 221 abstracts of which 17 met inclusion criteria and were reviewed (1 randomized-control trial, 13 retrospective cohort studies, and 3 meta-analyses)...

Repairing DNA double-strand breaks (DSBs) by nonhomologous end joining (NHEJ) requires multiple proteins to recognize and bind DNA ends, process them for compatibility, and ligate them together. We constructed novel DNA substrates for single-molecule nanomanipulation, allowing us to mechanically detect, probe, and rupture in real-time DSB synapsis by specific human NHEJ components. DNA-PKcs and Ku allow DNA end synapsis on the 100 ms timescale, and the addition of PAXX extends this lifetime to ~2 s. Further addition of XRCC4, XLF and ligase IV results in minute-scale synapsis and leads to robust repair of both strands of the nanomanipulated DNA...

Most eukaryotic parasites are obligately heteroxenous, requiring sequential infection of different host species in order to survive. Toxoplasma gondii is a rare exception to this rule, having a uniquely facultative heteroxenous life cycle. To understand the origins of this phenomenon, we compared development and stress responses in T. gondii to those of its its obligately heteroxenous relative, Hammondia hammondi and have identified multiple H. hammondi growth states that are distinct from those in T. gondii...

γ-Glutamyltranspeptidase (GGT) plays critical roles in regulating various physiological/pathophysiological processes including the intracellular redox homeostasis. However, an effective fluorescent probe for dissecting the relationships between GGT and oxidative stress in vivo remains largely unexplored. Herein, we present a light-up fluorescent probe (DCDHF-Glu) with long wavelength emission (613 nm) for the highly sensitive and selective detection of GGT using dicyanomethylenedihydrofuran derivative as the fluorescent reporter and γ-glutamyl group as the enzyme-active trigger...

A Merkel cell-neurite complex is a touch receptor composed of specialized epithelial cells named Merkel cells and peripheral sensory nerves in the skin. Merkel cells are found in touch-sensitive skin components including whisker follicles. The nerve fibers that innervate Merkel cells of a whisker follicle extend from the maxillary branch of the trigeminal ganglion. Whiskers as a sensory organ attribute to the complicated architecture of the Merkel cell-neurite complex, and therefore it is intriguing how the structure is formed...

The hyoid bone consists of a body and two pairs of processes: the greater cornua (GC) and the lesser cornua. The GC is connected to the superior thyroid cornu (STC) by the lateral thyrohyoid ligament. The GC and the STC share a common embryological origin from the third pharyngeal arch. During anatomical dissection of a male cadaver of 56 years of age, a combined variation of the GC and the STC was found. The left GC was 27.7 mm long, and the right GC was 30 mm long. The left GC axis was in the same plane as the hyoid body, while an angle of 33° was between the right GC axis and the hyoid body plane...

REVIEW
Pascal-Alexandre Thomas
Appropriate lymph node (LN) assessment is a hallmark of surgical quality of curative intent operations for non-small cell lung cancer (NSCLC). Even in the era of extensive pre-treatment work-up including routine PET-scanning and brain imaging, and selective invasive LN evaluation, unexpected LN metastases are found at surgery in more than 10% of patients with a cT1aN0 tumor. Systematic lymphadenectomy minimizes the risk of leaving tumor-LN behind and thus the risk of an incomplete resection, and provides the most truthful pTNM, which is decisive in directing adjuvant chemotherapy...

Background: The thyroid gland is resistant to microbial infection, because of its organ characteristics such as encapsulation, iodine content, and rich blood supply. Therefore, acute suppurative thyroiditis (AST), as a bacterial infection of the thyroid gland, is rarely seen. AST typically takes places on the left side the neck region in children, because of the coincidence of the left piriform sinus fistula, as a most common route of infection. AST is also usually seen in immunocompromised hosts...

The self-assembly of protein complexes is at the core of many fundamental biological processes 1 , ranging from the polymerization of cytoskeletal elements, such as microtubules 2 , to viral capsid formation and organelle assembly 3 . To reach a comprehensive understanding of the underlying mechanisms of self-assembly, high spatial and temporal resolutions must be attained. This is complicated by the need to not interfere with the reaction during the measurement. As self-assemblies are often governed by weak interactions, they are especially difficult to monitor with high-speed atomic force microscopy (HS-AFM) due to the non-negligible tip-sample interaction forces involved in current methods...

Protein composition at the plasma membrane is tightly regulated, with rapid protein internalization and selective targeting to the cell surface occurring in response to environmental changes. For example, ion channels are dynamically relocalized to or from the plasma membrane in response to physiological alterations, allowing cells and organisms to maintain osmotic and salt homeostasis. To identify additional factors that regulate the selective trafficking of a specific ion channel, we used a yeast model for a mammalian potassium channel, the K+ inwardly rectifying channel Kir2...
