The tRNA for the 21st proteinogenic amino acid, selenocysteine, exists in mammalian cells as 2 isoforms differing by a single 2'-O-methylribosyl moiety at position 34 (Um34). These isoforms contain either 5-methoxycarbonylmethyluridine (mcm(5)U) or 5-methoxycarbonylmethyl-2'-O-methyluridine (mcm(5)Um) at position 34. The accumulation of the mcm(5)Um isoform is tightly correlated with the expression of nonessential "stress response" selenoproteins such as glutathione peroxidase 1 (GPX1). The expression of essential selenoproteins, such as thioredoxin reductase 1 (TXNRD1), is not affected by changes in Sec-tRNA([Ser]Sec) isoform accumulation...

Peer support is recommended by the World Health Organization for the initiation and continuation of breastfeeding, and this recommendation is included in United Kingdom (U.K.) guidance. There is a lack of information about how, when, and where breastfeeding peer support was provided in the U.K. We aimed to generate an overview of how peer support is delivered in the U.K. and to gain an understanding of challenges for implementation. We surveyed all U.K. infant feeding coordinators (n = 696) who were part of U...

BACKGROUND/AIMS: Breast cancer (BCa) prognostication is a vital element for providing effective treatment for patients with BCa. Studies suggest that ethnicity plays a greater role in the incidence and poor prognosis of BCa in younger women than in their older counterparts. Therefore, the goal of this study was to assess the association between age and ethnicity on the overall final prognosis. MATERIALS AND METHODS: Nottingham Prognostic Index (NPI) was used to analyze BCa prognosis using Howard University Cancer Center Tumor Registry and the National Cancer Institute's Surveillance, Epidemiology, and End Results BCa datasets...

Hypertrophic cardiomyopathy (HCM) is the most common single gene inherited cardiomyopathy. In cats (Felix catus) HCM is even more prevalent and affects 16% of the outbred population and up to 26% in pedigree breeds such as Maine Coon and Ragdoll. Homozygous MYBPC3 mutations have been identified in these breeds but the mutations in other cats are unknown. At the clinical and physiological level feline HCM is closely analogous to human HCM but little is known about the primary causative mechanism. Most identified HCM causing mutations are in the genes coding for proteins of the sarcomere...

Psychosocial stress leads to the activation of kappa opioid receptors (KORs), which induce dysphoria and facilitate depression-like behaviors. However, less is known about the long-term effects of stress and KORs in females. We examined the long-term effects of social defeat stress on the aversive properties of KOR activation in male and female California mice (Peromyscus californicus) using a conditioned place aversion paradigm. Female California mice naïve to social defeat, formed a place aversion following treatment with 2...

Despite the growing number of studies showing that genotype × environment and epistatic interactions control fitness, the influences of epistasis × environment interactions on adaptive trait evolution remain largely uncharacterized. Across three field trials, we quantified aliphatic glucosinolate (GSL) defense chemistry, leaf damage, and relative fitness using mutant lines of Arabidopsis thaliana varying at pairs of causal aliphatic GSL defense genes to test the impact of epistatic and epistasis × environment interactions on adaptive trait variation...

BACKGROUND: Nipple-sparing techniques have improved the aesthetics of reconstruction following mastectomy, but nipple necrosis complicates up to 37% of procedures, distressing patients, delaying adjuvant therapy, and compromising outcomes. No method reliably detects nipple necrosis better than clinical assessment of tissue perfusion. We prospectively assessed the accuracy of intraoperative indocyanine green laser angiography to predict nipple necrosis. METHODS: Twenty consecutive women undergoing immediate tissue expander breast reconstruction following 32 nipple-sparing mastectomies underwent indocyanine green fluorescence imaging to assess nipple perfusion immediately before and after intraoperative tissue expansion...

Global deserts occupy one-third of the Earth's surface and contribute significantly to organic carbon storage, a process at risk in dryland ecosystems that are highly vulnerable to climate-driven ecosystem degradation. The forces controlling desert ecosystem degradation rates are poorly understood, particularly with respect to the relevance of the arid-soil microbiome. Here we document correlations between increasing aridity and soil bacterial and archaeal microbiome composition along arid to hyperarid transects traversing the Atacama Desert, Chile...

Vertebrate pigmentation is a process directed by various transcriptional regulators, that drive the specification of melanoblasts from neural crest cells, their proliferation and migration, and terminal differentiation into melanocytes, culminating in the generation of pigment and it's distribution to surrounding keratinocytes. The transcription factor MITF has been coined the "master regulator" of melanocyte development (reviewed in (Steingrímsson, Copeland and Jenkins, 2004)), as it drives both the specification and differentiation of melanocytes...

A 57 year old man was referred from an outside facility for an unresolving pneumonia. Imaging of the chest demonstrated a right lung mass with a consolidation in the middle lobe, pleural effusion, and mediastinal lymphadenopathy. Cytologic examination of cultures from the bronchoscopy and thoracentesis did not yield a definitive diagnosis. Video-assisted thoracoscopic surgery (VATS) was performed because of a retained hemothorax and a suggestive lesion. Biopsy specimens obtained during VATS were consistent with mucormycosis...

BACKGROUND AND IMPORTANCE: Tarlov cysts, also known as perineural cysts, have been described as meningeal dilations of the spinal nerve root sheath between the peri- and endoneurium at the dorsal root ganglion. Most often they are found in the sacrum involving the nerve roots. Normally asymptomatic, they have been reported to present with radiculopathy, paresthesias, and even urinary or bowel dysfunction. Sacral insufficiency has not been a well-documented presentation. CLINICAL PRESENTATION: The patient is a 38-year-old female who started to develop left low back pain and buttock pain that rapidly progressed into severe pain with some radiation down the posterior aspect of her left leg...

The distal dural ring (DDR) is a conserved intracranial anatomic structure marking the boundary point at which the internal carotid artery (ICA) exits the cavernous sinus (CS) and enters the subarachnoid space. Although the CS has been well described in a range of anatomic studies, to our knowledge no prior study has analyzed the histologic relationship between the ICA and DDR. Correspondingly, our objective was to assess the relationship of the DDR to the ICA and determine whether the DDR can be dissected from the ICA and thus divided, or can only be circumferentially trimmed around the artery...
