To gain more insight into central hearing loss, we investigated the relationship between cortical thickness and surface area, speech-relevant resting state EEG power, and above-threshold auditory measures in older adults and younger controls. Twenty-three older adults and 13 younger controls were tested with an adaptive auditory test battery to measure not only traditional pure-tone thresholds, but also above individual thresholds of temporal and spectral processing. The participants' speech recognition in noise (SiN) was evaluated, and a T1-weighted MRI image obtained for each participant...

It is well-accepted that inflammation plays an important role in the development of cardiac remodeling and that therapeutic approaches targeting inflammation can inhibit cardiac remodeling. Although a large amount of evidence indicates that activation of α7 nicotinic acetylcholine receptor (α7nAChR) causes an anti-inflammatory effect, the role of α7nAChR in cardiac remodeling and the underlying mechanism have not been established. To investigate the effect of the specific α7nAChR agonist, PNU282987, on cardiac remodeling induced by isoproterenol (ISO 60 mg/kg/d) in mice, the cardiomyocyte cross-sectional area (CSA) and collagen volume fraction were evaluated by hematoxylin and eosin (HE) and Masson staining, respectively...

: Ketamine's history begins in the 1950s in Detroit, Michigan, at Parke-Davis Laboratories. On 26 March 1956, Harold V. Maddox synthesised phencyclidine or PCP. Domino studied PCP effects in animals and in 1958, Greifenstein made the first trials of PCP in humans under the name of Sernyl. Sernyl did not cause depression of cardiovascular and respiratory functions, but elicited severe excitation with a very prolonged postoperative recovery. Because of its psychedelic effects, it became a street drug under the name of 'angel dust' and was placed on schedule II of Federal Controlled Substance Act (CSA) in 1978...

Macrophage activation syndrome (MAS) is a life-threating complication of systemic juvenile idiopathic arthritis (s-JIA). Steroid and cyclosporine (CsA) are effective for MAS, but, treatment for steroid- and CsA-resistant patients is still challenging. We report the case of steroid and CsA resistant s-JIA associated MAS misdiagnosed as Kawasaki disease (KD), who was successfully treated with the combination of plasma exchange (PE) and leukocytapheresis (LCAP) followed by plasma diafiltration (PDF). PE + LCAP effectively removed proinflammatory cytokines and reduced the number of peripheral white blood cells...

A direct and efficient introduction of a trifluoroethylamine motif into various heteroaromatic structures, using a readily available xanthate S-[1-(N-acetylamino)-2,2,2-trifluoroethyl]-O-ethyl dithiocarbonate (5), is reported. Medicinally relevant trifluoroethylaminated heteroarenes containing a wide range of functional groups were successfully synthesized under mild conditions. This amide isostere could be introduced into both electron-rich and -poor heteroarenes to give the desired products in one step. The beneficial effect of camphorsulfonic acid (CSA) was also demonstrated with electron-deficient heteroarenes...

Honokiol (HNK) is a small molecule with potent anti-inflammatory and anti-tumorigenic properties; yet the molecular targets of HNK are not well studied. Hyperactivation of the receptor tyrosine kinase c-Met and overexpression of the cytoprotective enzyme heme oxygenase-1 (HO-1) play a critical role in the growth and progression of renal cell carcinoma (RCC). Interestingly, the calcineurin inhibitor (CNI) cyclosporine A (CsA), an immunosuppressant used to prevent allograft rejection, can also increase the risk of RCC in transplant patients...

PURPOSE: Capillary regression is commonly observed in response to disuse muscle atrophy. Heat stress is known to alleviate muscle atrophy, while effect of heat exposure on capillary adaptation following disuse atrophy is not defined. Here, we examined the effect of heat treatment on capillarisation and the associated signalling in slow-oxidative soleus and fast-glycolytic plantaris muscles following Achilles tendon ablation (tenotomy). MATERIALS AND METHODS: Male Wistar rats were assigned into control (CON), control with heat stress (CON + HEAT), tenotomy (TEN) and tenotomy with heat stress (TEN + HEAT) groups...

This study used an important data set to examine long-term adjustment and functioning in men, who as adolescents had sexual experiences with men. The data came from the National Health and Social Life Survey, which used a national probability sample (Laumann, Gagnon, Michael, & Michaels, 1994). Three perspectives were considered, which offered different predictions. From the "child sexual abuse" (CSA) paradigm, which dominates clinical, legal, and lay views, expected was robust evidence for poorer adjustment, given that intense harm is assumed to be intrinsic...

BACKGROUND: Posttraumatic Stress Disorder (PTSD) related to childhood sexual abuse (CSA) is often associated with a wide range of trauma-related aversive emotions such as fear, disgust, sadness, shame, guilt, and anger. Intense experience of aversive emotions in particular has been linked to higher psychopathology in trauma survivors. Most established psychosocial treatments aim to reduce avoidance of trauma-related memories and associated emotions. Interventions based on Dialectical Behavior Therapy (DBT) also foster radical acceptance of the traumatic event...

Test-retest reliability of the combined process of ultrasound imaging (USI) and image measurement of thickness of abdominal and upper lumbar multifidus (MF) muscles and MF cross sectional area (CSA) of older adults has not been established. Imaging muscles of older adults can be challenging due to age-related changes in the spine and skeletal muscle so establishing test-retest reliability in this population is important. This study aimed to evaluate test-retest reliability of USI of abdominal and MF muscle thickness and MF CSA for adults aged 50-79 years...

Child sexual abuse remains an underreported crime throughout the world, despite extensive research and resources dedicated both to improving investigative techniques and helping children disclose their experiences. The discovery of rampant cover-ups within the Catholic Church has exposed some of the ways religious and cultural issues can impede reporting to authorities. This article examines specific factors that contribute to the underreporting of child sexual abuse within Orthodox Jewish communities. It also explores ways in which these communities have handled child sexual abuse reporting in the past and describes recent progress...

The Drug Enforcement Administration (DEA) is finalizing the designation of the chemical alpha-phenylacetoacetonitrile (APAAN) and its salts, optical isomers, and salts of optical isomers, as a list I chemical under the Controlled Substances Act (CSA). The DEA proposed control of APAAN, due to its use in clandestine laboratories to illicitly manufacture the schedule II controlled substances phenylacetone (also known as phenyl-2-propanone or P2P), methamphetamine, and amphetamine. This rulemaking finalizes, without change, the control of APAAN as a list I chemical...

BACKGROUND: Nonomuraea dietziae is a promising microorganism to mediate the region-specific monooxygenation reaction of cyclosporine A (CsA). The main product [(4'-OH)MeLeu](4)-CsA possesses high anti-HIV/HCV and hair growth-stimulating activities while avoiding the immunosuppressive effect of CsA. However, the low conversion efficiency restricts the clinical application. In this study, the production of [(4'-OH)MeLeu](4)-CsA was greatly improved by 55.6% from 182.8 to 284.4 mg/L when supplementing soybean oil into the production medium, which represented the highest production of [(4'-OH)MeLeu](4)-CsA so far...

PURPOSE: The SANSIKA study evaluated the efficacy/safety of 0.1% (1 mg/mL) cyclosporine A cationic emulsion (CsA CE) for treating dry eye disease (DED) with severe keratitis. The double-masked phase demonstrated that CsA CE was effective in reducing corneal damage and ocular surface inflammation, and was well-tolerated over 6 months. Here we report efficacy and safety findings of SANSIKA's open-label extension (OLE). METHODS: In this multicenter, double-masked, phase III study, patients with severe DED (corneal fluorescein staining [CFS] grade 4, modified Oxford scale) were randomized to once-daily CsA CE (Ikervis®) or its vehicle for 6 months, followed by 6-month open-label, once-daily CsA CE (CsA CE/CsA CE and vehicle/CsA CE groups)...

Loss of muscle mass during periods of disuse likely has negative health consequences for older adults. We have previously shown that β-hydroxy-β-methylbutyrate (HMB) supplementation during 10 days of strict bed rest (BR) attenuates the loss of lean mass in older adults. To elucidate potential molecular mechanisms of HMB effects on muscle during bed rest and resistance training rehabilitation (RT), we examined mediators of skeletal muscle mitochondrial dynamics, autophagy and atrophy, and intramyocellular lipids...

Accurate diagnosis of subtypes of transverse sinus (TS) hypoplasia requires more expensive methods like magnetic resonance (MR) imaging. We hypothesized ultrasound findings of the internal jugular vein (IJV) can be surrogate indicators for diagnosis of TS hypoplasia. MR images were reviewed in 131 subjects to evaluate TS diameter and the location and degree of venous flow stenosis and obstruction. Ultrasound parameters including the cross-sectional lumen area (CSA), time-average-mean velocity (TAMV), and flow volume (FV) at each IJV segment were also evaluated...

BACKGROUND: Circulating endothelial cells (CECs) are widely reported as a promising biomarker of endothelial damage/dysfunction in coronary artery disease (CAD). The two popular methods of CEC quantification include the use of immunomagnetic beads separation (IB) and flow cytometry analysis (FC); however, they suffer from two main shortcomings that affect their diagnostic and prognostic responses: non-specific bindings of magnetic beads to non-target cells and a high degree of variability in rare cell identification, respectively...
