It is still challenging to detect endolymphatic hydrops (EH) in patients with Meniere's disease (MD) using MRI. The aim of the present study was to optimize a sensitive technique generating strong contrast enhancement from minimum gadolinium-diethylenetriamine pentaacetic acid (Gd-DTPA) while reliably detecting EH in the inner ear, including the apex.

All imaging was performed using a3.0T MR system 24h after intratympanic injection of low-dose Gd-DTPA. Heavily T2-weighted 3-dimensional fluid-attenuated inversion recovery reconstructed with magnitude and zero-filled interpolation (hT

W-FLAIR-ZFI) was optimized and validated in phantom studies and compared with medium inversion time inversion recovery imaging with magnitude reconstruction (MIIRMR). The following parameters were used in hT

W-FLAIR-ZFI repetition time 14,000ms, echo time 663ms, inversion time 2900ms, flip angle 120°, echo train length 271, and field of view 166 × 196mm

.

MRI obtained using hT

W-FLAIR-MZFI yielded high-quality images with sharper and smoother borders between the endolymph and perilymph and a higher signal intensity ratio and more homogenous perilymph enhancement than those generated with MIIRMR (p < 0.01). There were predominantly grade II EHs in the cochleae and grade III EHs in the vestibule in definite MD. EH was detected in the apex of 11/16 ipsilateral ears, 3/16 contralateral ears in unilateral definite MD and 3/6 ears in bilateral MD.

The novel hT

W-FLAIR-MZFI technique is sensitive and demonstrates strong and homogenous enhancement by minimum Gd-DTPA in the inner ear, including the apex, and yields high-quality images with sharp borders between the endolymph and perilymph.

To investigate the association of oral health condition with the occurrence of medication-related osteonecrosis of the jaw (MRONJ) in a cancer population.

A multicenter cross-sectional study was conducted with cancer patients exposed to bisphosphonates for at least 7months. Dental and periodontal conditions were assessed by epidemiological indices.

The sample consisted of 80 patients under bisphosphonate therapy, nine of which were allocated to group 1 (with MRONJ) and 71 to group 2 (without MRONJ). Osteonecrosis cases presented 19 decayed, missing, and filled teeth on average. Moderate gingival inflammation was noted in both groups and together with severe inflammation exceeded 50% of the groups. The presence of dental calculus was detected in about half of the individuals in both groups. Shallow periodontal pockets were detected in about 25% of both groups. Deep periodontal pockets were more prevalent among patients with osteonecrosis. Regular oral hygiene was detected in approximately 25% of individuals in both groups. There was a strong positive correlation between the clinical staging of osteonecrosis and decayed, missing, and filled teeth index (DMFTI).

Patients had a poor oral health condition. All but one osteonecrosis case had no previous history of tooth extraction; oral infections seemed to play a major role in the development of bone necrosis. Advanced osteonecrosis stages were associated with a higher DMFTI.

Vascular changes were assessed using a photoplethysmograph that aimed to detect changes in pelvic vasocongestion. An important advantage of detecting sexual response within the anal canal is that the device, its anatomical placement, and the data output are identical for women and men, therefore facilitating gender comparisons of response patterns. In this study, the vaginal photoplethysmograph (VPP), the most common measure of genital response in women, was administered intra-anally as an anal photoplethysmograph (APG) to examine its validity and sensitivity as an indicator of sexual response. Brepocitinib in vitro The final sample comprised 20 women and 20 men who were exposed to 12, 90-s sexual and nonsexual film clips while their APG responses were recorded. Participants also rated their sexual arousal and affective responses to the stimuli. There was evidence that APG responses were specific to sexual stimuli and were sensitive to erotic intensity in women. The degree of discrimination between sexual and nonsexual stimuli was lower in men. Unlike most sexual psychophysiological studies, the positive correlation between physiological and self-reported sexual arousal was stronger in women than in men. There was a relatively high number of data artifacts and the waveform morphology was uncharacteristic of that typically observed with VPP. The potential role of anal musculature interference on the APG signal is discussed, as well as avenues for future research.

To assess the performance change and physiological adaptations following nine sessions of short high-intensity interval training (HIIT) or sprint-interval training (SIT) in sprint kayakers.

Twelve trained kayakers performed an incremental test and 3 time trials (200m, 500m and 1000m) on a kayak ergometer. Oxygen consumption (V̇O

) and muscle oxygenation of the latissimus dorsi, biceps brachii, and vastus lateralis were measured. Athletes were then paired for sex and V̇O

max and randomized into a HIIT or a SIT training group, and performed nine training sessions before repeating the tests.

Training improved performance in HIIT (200m + 3.8 ± 3.1%, p = 0.06; 500m + 2.1 ± 4.1%, p = 0.056; 1000m + 3.0 ± 4.6%, p = 0.13) but changes in performance remained within the smallest worthwhile change in SIT (200m + 0.8 ± 4.1%, p = 0.59; 500m + 0.5 ± 4.1%, p = 0.87; 1000m + 1.3 ± 4.6%, p = 0.57). In the 1000m, training led to a greater deoxygenation in the biceps brachii and vastus lateralis in HIIT, and in the latintribution of peripheral adaptations to performance in sprint kayaking.

Tubular injury plays a crucial role in the pathogenesis of diabetic nephropathy (DN). link2 It is well known that many microRNAs (miRNAs) exert crucial effects on tubular injury. This study intends to explore the effect of miR-142-3p on the apoptosis and oxidative stress of high glucose (HG)-treated renal tubular epithelial cells (HK-2) and its underlying mechanism.

HK-2 cells were exposed to HG to mimic cell injury. MTT assays and flow cytometry analyses were conducted to measure cell viability and cell apoptosis, respectively. RT-qPCR and western blot analyses were carried out to detect RNA and protein levels, respectively. link3 The levels of oxidative stress markers were evaluated by ELISA. The binding between miR-142-3p and biorientation of chromosomes in cell division 1 (BOD1) was validated by a luciferase reporter assay.

MiR-142-3p is low-expressed in HG-stimulated HK-2 cells. Functionally, miR-142-3p overexpression attenuates the apoptosis and oxidative stress of HG-stimulated HK-2 cells. Mechanistically, BOD1 was confirmed to be targeted by miR-142-3p in HK-2 cells. Moreover, BOD1 overexpression reversed the suppressive effect of miR-142-3p overexpression on the apoptosis and oxidative stress of HK-2 cells treated with HG.

MiR-142-3p ameliorates HG-induced renal tubular epithelial cell injury by targeting BOD1. The finding might provide novel insight into the role of miR-142-3p/BOD1 axis in DN treatment.

Accurate preoperative T staging is important when determining the treatment strategy for advanced colorectal cancer. We have previously reported the usefulness of preoperative T staging based on the spatial relationship of tumors and "bordering vessels" by computed tomography colonography (CTC) with multiplanar reconstruction (MPR). The aims of this study were to evaluate the external validity of this method and to determine whether there is a difference in the accuracy of T staging between the mesenteric and antimesenteric sides.

The study subjects were 110 patients with colorectal cancer who underwent preoperative CTC and surgical resection from June 2016 to March 2018. Preoperative T stage was determined by CTC based on the relationship between the tumor and the bordering vessels and compared with the pathological T stage. The influence of tumor location, namely, whether the tumor was on the antimesenteric or mesenteric side, on preoperative T staging was assessed in 78 patients with colorectal cancer.

Sensitivity, specificity, accuracy, positive, and negative predictive values were respectively, 65%, 91%, 83%, 76%, and 85% for T2 (n = 34); 76%, 82%, 81%, 50%, and 94% for T3 (n = 23); and 77%, 93%, 87%, 86%, and 88% for T4a disease (n = 39). Overall right answer rate was 83.3% (15/18) for the mesenteric side and 65% (39/60) for the antimesenteric side (n = 0.14).

Diagnostic criteria based on the bordering vessels seen on CTC images with MPR are useful for T staging of colorectal cancer. However, the accuracy differs between the antimesenteric and mesenteric sides.

MM is subclassified into high and standard risk based on cytogenetic and laboratory markers. The treatment of newly diagnosed multiple myeloma is constantly changing with the advent of novel therapies. Recent advances in therapies have resulted in longer time to remission and overall survival. the introduction of targeted therapy with monoclonal antibodies such as Daratumumab has improved stringent complete response to 39%. In this review, we outline the current approach to diagnosis, prognosis, and management of newly diagnosed multiple myeloma in both transplant eligible and ineligible patients.The Metabolic Theory of Ecology (MTE) predicts that the temperature increases exert a common effect on organisms stimulating metabolic rates, this being stronger for a heterotrophic than for an autotrophic metabolism. However, no available studies within the MTE framework have focused on organisms' response under fluctuation at high temperature interacting with factors such as nutrient availability, or how this interaction could affect the coexistence between mixotrophic and strict autotrophic phytoplankton. Hence, we assess how the phytoplankton metabolism and species composition are affected under scenarios of high temperature and fluctuation at high temperature, and how nutrients alter the direction and magnitude of such impact. For that, we use a mixed culture composed of two phytoplankton species a strict autotrophic species and a mixotrophic species. Our results indicate that, in agreement with the MTE, only fluctuation at high temperature treatment registered a greater activation energy (Ea) value for respiration than for primary production and stimulated mixotrophic over strict autotrophic species abundance compared to control treatment.
