    More important, elevated taste bud renewal and dysgeusia recovery toward sweetness were observed in RIOM mice treated with LiCl as compared to those treated by KGF. Collectively, our data demonstrate that LiCl can mitigate oral mucositis and rescue taste alteration induced by irradiation, and activation of Wnt/β-catenin signaling may represent a promising therapy to improve the quality of life of patients receiving radiotherapy.Adamantinoma-like Ewing sarcoma is a rare variant of Ewing sarcoma with histologic and immunohistochemical evidence of squamous differentiation. Oridonin mouse This variant most commonly occurs in the head and neck region with a few cases reported in the long bones of the limbs. It may be associated with poorer clinical outcome and could pose a diagnostic challenge, particularly if it occurs in older patients or as a metastatic lesion. We present a case of Ewing sarcoma in the metatarsal of an 11-year-old boy that manifested adamantinoma-like morphology after neoadjuvant chemotherapy. Chemotherapy has been reported to induce neuronal maturation and rhabdoid morphology in cases of Ewing sarcoma, but no reports of treatment-induced squamous differentiation with P40/P63 expression have been demonstrated. This is also the first documented case treated with a pedicled osteocutaneous fibular transfer in a metatarsal malignancy, which is usually treated by either ray or below-knee amputation.Though previous research has examined survivors’ use of formal and informal services, less research has looked at whether sexual orientation, race, and different sexual assault types (e.g., coercive) are associated with seeking support services. The purpose of this study is to examine factors associated with utilizing services or support from informal sources (e.g., telling a friend) and formal sources (e.g., psychological counseling) following a sexual assault. Data were gathered in Fall and Spring of 2019-2020 from undergraduate students at a Midwestern university. Logistic regression results showed that heterosexual students had 56% lower odds of using informal supports, while females were 2.05 times more likely to have used informal supports compared to their counterparts. Students who reported more heavy drinking had 37% lower odds of using informal supports compared to their counterparts. Those who experienced physical and incapacitated sexual assault were 2.09 times and 3.60 times more likely to have used informal supports, respectively. Additionally, older students were 1.35 times more likely to have used formal supports compared to younger students, whereas heterosexual students had 67% lower odds of using formal supports compared to sexual minority students. Those with greater PTSD symptoms were 1.07 times more likely to access formal services. Finally, students with greater depressive symptoms had 8% lower odds of using formal supports. Identifying college students who are less likely to access support services following a sexual assault has important implications for targeted prevention and intervention.Easy access to high-calorie and fat-dense fast food has resulted in unhealthy dietary and lifestyle changes worldwide, which affects both developed and developing economies. This predisposes populations to a considerable number of metabolic and inflammatory conditions, such as diabetes, nonalcoholic fatty liver disease (NAFLD), and cardiovascular disease (CVD). Guinea pigs have been proposed as a model to study high-fat diet-induced metabolic disease due to their similar antioxidant metabolism and lipid profile to humans, and their susceptibility to atherosclerosis and endothelial disease. This study aims to evaluate cardiovascular and metabolic disorders induced by high-fat high-sucrose diet (HFHSD) in guinea pigs. Two to three-week-old male guinea pigs were fed a normal diet (ND) or HFHSD for 12 wk. Guinea pigs fed a HFHSD developed glucose intolerance, dyslipidemia, and liver, cardiac, and kidney damage. However, hypertension, dysautonomia, endothelial disease, and obesity were absent in these HFHSD guinea pigs. Taken together, these results show that guinea pigs fed a HFHSD are a nonobese model of metabolic disorders, resulting in important cardiac damage. Moreover, our findings suggest that NAFLD may be an important risk factor for diet-induced CVD.NEW & NOTEWORTHY In this study, we show a new animal model for diet-induced disease metabolic disorders without obesity in guinea pigs. Moreover, results suggest a strong relation between liver disease and increased cardiovascular risks.Work of breathing ([Formula see text]) derived from a single lung volume and pleural pressure is limited and does not fully characterize the mechanical work done by the respiratory musculature. It has long been known that abdominal activation increases with increasing exercise intensity, yet the mechanical work done by these muscles is not reflected in [Formula see text]. Using optoelectronic plethysmography (OEP), we sought to show first that the volumes obtained from OEP (VCW) were comparable to volumes obtained from flow integration (Vt) during cycling and running, and second, to show that partitioned volume from OEP could be utilized to quantify the mechanical work done by the rib cage ([Formula see text]RC) and abdomen ([Formula see text]AB) during exercise. We fit 11 subjects (6 males/5 females) with reflective markers and balloon catheters. Subjects completed an incremental ramp cycling test to exhaustion and a series of submaximal running trials. We found good agreement between VCW versus Vt during cycise. Collectively, our findings indicate that pulmonary mechanics can be accurately quantified using OEP, and abdominal work performed during ventilation contributes substantially to the overall work of the respiratory musculature.Muscle atrophy and decline in muscle strength appear very rapidly with prolonged disuse or mechanical unloading after acute hospitalization or experimental bed rest. The current study analyzed data from short-, medium-, and long-term bed rest (5-120 days) in a pooled sample of 318 healthy adults and modeled the mathematical relationship between muscle strength decline and atrophy. The results show a logarithmic disuse-induced loss of strength and muscle atrophy of the weight-bearing knee extensor muscles. The greatest rate of muscle strength decline and atrophy occurred in the earliest stages of bed rest, plateauing later, and likely contributed to the rapid neuromuscular loss of function in the early period. In addition, during the first two weeks of bed rest, muscle strength decline is much faster than muscle atrophy on day 5, the ratio of muscle atrophy to strength decline as a function of bed rest duration is 4.2, falls to 2.4 on day 14, and stabilizes to a value of 1.9 after about 35 days of bed rest. Positive regression revealed that approximately 79% of the muscle strength loss may be explained by muscle atrophy, while the remaining is most likely due to alterations in single fiber mechanical properties, excitation-contraction coupling, fiber architecture, tendon stiffness, muscle denervation, neuromuscular junction damage and supraspinal changes.
