Comparison of Pure-Tone Average Methods for Estimation of Hearing Loss Caused by Environmental Exposure to Lead and Cadmium: Does the Pure-Tone Average Method Which Uses Low-Frequency Ranges Underestimate the Actual Hearing Loss Caused by Environmental Lead and Cadmium Exposure?

Audiol Neurootol 2018 Dec 11;23(5):259-269. Epub 2018 Dec 11.

BK21 PLUS Program in Embodiment: Health-Society Interaction, Department of Public Health Sciences, Graduate School, Korea University, Seoul, Republic of Korea.

Previous studies have reported that exposure to lead and cadmium can damage the inner ear receptor, which perceives high-frequency sounds. However, few studies have used the pure-tone average (PTA), including high-frequency ranges, for the estimation of hearing loss caused by lead and cadmium exposure. We estimated hearing loss using the PTA test, in low-frequency, speech frequency, and high-frequency ranges and compared the differences in the results using 3 PTA calculation methods. Read More

Individualized Hemodialysis Treatment: A Perspective on Residual Kidney Function and Precision Medicine in Nephrology.

Cardiorenal Med 2018 Dec 11;9(2):69-82. Epub 2018 Dec 11.

Harold Simmons Center of Kidney Disease Research and Epidemiology, Division of Nephrology and Hypertension, University of California Irvine School of Medicine, Orange, California,

Background: Residual kidney function (RKF) is often expected to inevitably and rapidly decline among hemodialysis patients and, hence, has been inadvertently ignored in clinical practice. The importance of RKF has been revisited in some recent studies. Given that patients with end-stage renal disease now tend to initiate maintenance hemodialysis therapy with higher RKF levels, there seem to be important opportunities for incremental hemo-dialysis by individualizing the dose and frequency according to their RKF levels.

The presence of the low molecular mass carbonic anhydrase in photosystem II of C3 higher plants.

J Plant Physiol 2018 Nov 20;232:94-99. Epub 2018 Nov 20.

Institute of Basic Biological Problems of Russian Academy of Sciences, Pushchino, Moscow Region, 142290, Russia.

The carrier of carbonic anhydrase (CA) activity was detected in gel among low molecular mass proteins from pea, spinach and Arabidopsis, after nondenaturing electrophoresis in PAAG of the dodecyl-β-d-maltoside treated PSII membranes (the fragments of thylakoid membrane containing PSII complexes). The elimination of Mn-stabilizing protein PsbO by treatment of PSII membranes with salts, did not lead to a decrease in CA activity observed in the gel although it reduced the amount of this protein down to 25% compared to the original sample. The isolated protein PsbO did not demonstrated CA activity. Read More

Understanding nitrate contamination based on the relationship between changes in groundwater levels and changes in water quality with precipitation fluctuations.

Sci Total Environ 2018 Dec 5;657:146-153. Epub 2018 Dec 5.

Center for Water Cycle, Marine Environment and Disaster Management, Kumamoto University, Japan.

There are growing concerns about nitrate contamination in Kumamoto City, where >700,000 people completely depend on groundwater as a source of drinking water. We found that some groundwater samples showed considerably different nitrate concentrations although their sampling locations were close to one another, and we speculated that this phenomenon was due to the differences in subsurface geological properties. In order to verify this hypothesis, we carried out temporally intensive long-term monitoring of the groundwater levels and water qualities at three of the closely related sampling wells, and the results revealed that the changes in water level and water quality were different at each well.

On Cuba, diplomats, ultrasound, and intermodulation distortion.

Comput Biol Med 2018 Nov 22;104:250-266. Epub 2018 Nov 22.

Department of Systems Science and Engineering, Zhejiang University, China. Electronic address:

This paper analyzes how ultrasounds could have unintentionally led to the AP news recordings of metallic sounds heard by diplomats in Cuba. Beginning with screen shots of the acoustic spectral plots from the AP news, we reverse engineered ultrasonic signals that could lead to those outcomes as a result of intermodulation distortion with non-linearity in the acoustic transmission medium. We created a proof of concept ultrasonic device that amplitude modulates a signal over an inaudible ultrasonic carrier. Read More

Rickettsioses: Cutaneous findings frequently lead to diagnosis - a review.

J Dtsch Dermatol Ges 2018 Dec;16(12):1459-1476

While epidemic typhus caused by Rickettsia prowazekii posed a significant threat in Europe before and throughout World War II due to its high mortality, the condition fortunately no longer plays a significant role. Nevertheless, rickettsioses, such as African tick bite fever, have been increasingly diagnosed in travelers returning from sub-Saharan Africa. Caused by Rickettsia africae, African tick bite fever presents with characteristic cutaneous findings such as eschar (tache noir) and a rash. Read More

Markers of Accelerated Skeletal Muscle Regenerative Response in MRL/MpJ Mice: Characteristics of Muscle Progenitor Cells and Circulating Factors.

Stem Cells 2018 Dec 10. Epub 2018 Dec 10.

Department of Orthopaedic Surgery, McGovern Medical School, The University of Texas Health Science Center at Houston, Houston, Texas, USA.

The "super-healing" Murphy Roths Large (MRL/MpJ) mouse possesses a superior regenerative capacity for repair of many tissues, which makes it an excellent animal model for studying molecular and cellular mechanisms during tissue regeneration. Since the role of muscle progenitor cells (MPCs) in muscle healing capacity of MRL/MpJ mice has not been previously studied, we investigated the muscle regenerative capacity of MRL/MpJ mice following muscle injury, and the results were compared to results from C57BL/6 J (B6) age-matched control mice. Our results show that muscle healing upon cardiotoxin injury was accelerated in MRL/MpJ mice and characterized by reduced necrotic muscle area, reduced macrophage infiltration, and more regenerated myofibers (eMyHC+/centronucleated fibers) at 3, 5, and 12 days post-injury, when compared to B6 age-matched control mice.

Safe Casting and Reliable Cusp Reconstruction Assisted by Micro-Computed Tomographic Scans of Fossil Teeth.

Anat Rec (Hoboken) 2018 Dec 8. Epub 2018 Dec 8.

Department of Anthropology, The Ohio State University, 4034 Smith Laboratory, 174 West 18th Ave., Columbus, OH 43210, USA.

Dental replicas are frequently utilized in paleoanthropological studies of perikymata and enamel hypoplasia. However, fossil teeth are often fragile and worn, causing two problems: (1) the risk of damage by removing enamel fragments when impression-making material is separated from the fossil tooth surface, and (2) the need to reconstruct worn portions of the crown to assess perikymata number, distribution, and hypoplasia timing. This study presents the advantages of μCT data of canines and lateral incisors for (1) detecting cracks along the enamel-dentine junction (EDJ) which could cause damage when casting, and (2) reliably and non-destructively reconstructing worn or broken cusps.

There and back again - The journey of LiNiO₂ as cathode active material.

Angew Chem Int Ed Engl 2018 Dec 10. Epub 2018 Dec 10.

Universität Gießen, Heinrich-Buff-Ring 58, 35392, Gießen, GERMANY.

LiNiO₂ (LNO) has been introduced as cathode active material (CAM) for Li-ion batteries in 1990. After years of intensive research, it emerged that several instability issues plague the material, so that it was abandoned in favor of isostructural metal-substituted compounds called NCA (for lithium nickel cobalt aluminum oxide) and NCM (lithium nickel cobalt manganese oxide). These sacrifice a certain amount of specific energy in exchange for stability, durability and safety. Read More

Differential regulation of intestinal and hepatic CYP3A by 1α,25-dihydroxyvitamin D : Effects on in vivo oral absorption and disposition of buspirone in rats.

Drug Dev Res 2018 Dec 10. Epub 2018 Dec 10.

Department of Manufacturing Pharmacy, College of Pharmacy, Pusan National University, Busan, South Korea.

1α,25-Dihydroxyvitamin D (also called 1,25(OH) D or calcitriol) is the biologically active form of vitamin D, which functions as a ligand to the vitamin D receptor (VDR). It was previously reported that intestinal cytochrome P450 3A (CYP3A) expression was altered by 1,25(OH) D -mediated VDR activation. However, to clarify whether the change in CYP3A subfamily expression by VDR activation can affect metabolic function, further evidence is needed to prove the effect of 1,25(OH) D treatment on CYP3A-mediated drug metabolism and pharmacokinetics.

What role does pyroptosis play in microbial infection?

J Cell Physiol 2018 Dec 7. Epub 2018 Dec 7.

College of Animal Science and Veterinary Medicine, Henan Institute of Science and Technology, Xinxiang, China.

Pyroptosis, a type of programmed cell death mediated by gasdermin, is characterized by the swelling and rupture of cells, release of cellular contents and a strong inflammatory response, which is critical for controlling microbial infection. Pattern recognition receptors recognize the intracellular and extracellular pathogenic microbial components and stimulate the organism's inflammatory response by activating the pyroptosis signaling pathway and releasing interleukin-1β (IL-1β), IL-18, and other inflammatory factors to promote pathogen clearance and prevent infection. In the process of continuous evolution, pathogens have developed multiple strategies to modulate the occurrence of pyroptosis and thus enhance their ability to induce disease; that is, the competition between host cells and pathogens controls the occurrence of pyroptosis.

Influenza A virus (IAV), a highly pathogenic virus to human beings, is most susceptible to mutation and thus causes rapid, severe global pandemics resulting in millions of fatalities worldwide. Since resistance to the existing anti-influenza drugs is developing, innovative inhibitors with a different mode of action are urgently needed. The lead compound 6092B-E5 has proven to be an effective antiviral reagent in our previous work. Read More

Age-associated changes of resting energy expenditure, body composition and fat distribution in Chinese Han males.

Physiol Rep 2018 Dec;6(23):e13940

Department of Geriatrics, The First Affiliated Hospital of Nanjing Medical University, Nanjing, China.

Age-related alterations in whole body composition, particularly, reduced fat free mass (FFM) and increased fat mass (FM), lead to a progressive decline in resting energy expenditure (REE). Similarly, regional body composition and fat distribution changes with age might also contribute to an overall lower REE. This study investigated the influence of age on REE, regional body composition and fat distribution, including subcutaneous fat (SF) and visceral fat (VF), in a Chinese Han population as well as their contributions to age-related changes in REE.

Atrial fibrillation in β-thalassemia patients with a focus on the role of iron-overload and oxidative stress: A review.

J Cell Physiol 2018 Dec 10. Epub 2018 Dec 10.

Department of Clinical Pharmacy, School of Pharmacy, Mashhad University of Medical Sciences, Mashhad, Iran.

Cardiac complications including arrhythmia and especially atrial fibrillation (AF) are common causes of death in β-thalassemia patients. The main factor in the etiopathogenesis of these complications is iron overload, which results in increased oxidative stress. Although there is a known association between cardiac complications and iron overload in β-thalassemia patients, there is no comprehensive review on AF and excessive iron with a focus on oxidative stress in these patients.

Nurs Forum 2018 Dec 9. Epub 2018 Dec 9.

Center of Innovation in Long-Term Services and Supports, Providence VA Medical Center, Providence, RI.

Natural disasters impact people of every age in the communities where they occur, with older adults being a vulnerable subset of the population. Most disaster shelter volunteer nurses are experienced in addressing common health needs of older adult clients such as diabetes, hypertension, and pulmonary disease. These nurses also have the requisite training to respond to more acute medical events, including the symptoms of a heart attack or stroke. Read More

Maximum likelihood estimation of generalized linear models for adaptive designs: Applications and asymptotics.

Biom J 2018 Dec 10. Epub 2018 Dec 10.

Department of Mathematics and Statistics, Memorial University, St. John's, NL, Canada.

Due to increasing discoveries of biomarkers and observed diversity among patients, there is growing interest in personalized medicine for the purpose of increasing the well-being of patients (ethics) and extending human life. In fact, these biomarkers and observed heterogeneity among patients are useful covariates that can be used to achieve the ethical goals of clinical trials and improving the efficiency of statistical inference. Covariate-adjusted response-adaptive (CARA) design was developed to use information in such covariates in randomization to maximize the well-being of participating patients as well as increase the efficiency of statistical inference at the end of a clinical trial.
