Cannabidiol (CBD) has poor water solubility and is subjected to extensive first-pass metabolism. These absorption obstacles are responsible for low and variable oral bioavailability of CBD. This study endeavored to improve CBD bioavailability by intramuscular (IM) injection of CBD nanocrystals (CBD-NC). The nanocrystals were prepared by antisolvent precipitation method and were characterized in terms of the particle size, polydispersity index (PDI), zeta potential, morphology, and crystalline status. CBD-NC displayed a particle size of 141.7±1.5 nm, a PDI of 0.18±0.01, and a zeta potential of -25.73 mV. CBD-NC freeze-dried powder using bovine serum albumin (BSA) as cryoprotectant had good redispersibility, and the average particle size was 139.1±1.4 nm after reconstitution. Moreover, these freeze-dried powders were characterized for drug loading and pH and were evaluated for in vitro dissolution and in vivo studies in a rat model. The in vivo results showed that AUC0-24 h and Cmax of CBD by IM injection of CBD nanocrystals increased significantly compared with that of oral (P.O) administration of CBD nanocrystals and CBD oil solution. This underlines the nano-sized CBD could be suggested as a practical and simple nanosystem for IM delivery with improved bioavailability. More importantly, these results pave the way for future development of CBD-NC retentive dosage forms. Graphical abstract.The Brahmapur is the southernmost sub-division of Ganjam district of the Odisha coast frequently prone to cyclones. This coastal stretch is one of the low-lying areas of Odisha with dense population. Recent severe cyclones such as Phailin and Titli crossed the considered coastal stretch in 2013 and 2018 respectively causing severe damages to life and property. Identification of the coastal vulnerability index of such low lying areas is vital to plan effective mitigation measures and better preparedness to hazards. In this view, the Coastal Vulnerability Index (CVI) of the coastal stretch was attempted in the present study using analytical hierarchical process (AHP). The Physical Vulnerability Index (PVI) and Social Vulnerability Index (SVI) were integrated to obtain the Coastal Vulnerability Index. The approach of the study included pair-wise ranking of parameters based on their relevance and importance to the objective of the study. Trilaciclib clinical trial The CVI assessment indicated 22.2% of the coastal stretch with very high risk, 44.5% with high and 24.4% with moderate risk stretches with discontinuous small stretches of 9% with low-risk areas. The outcome of the study was validated with the cyclone crossing tracks of Phailin and Titli which exhibited good correlation with the CVI zones identified from the study. The determined vulnerable zones are useful for mitigation measures and better preparedness during such cyclone hazards in future. Advance techniques of Remote Sensing and Geographic Information System (GIS) integrated spatially with AHP derived data were used in the present study.

Macromastia often leads to physical complaints involving pain in the shoulder/neck area. In Germany, there are virtually no reliable data on the effects of breast reduction surgery with regard to neck and spine complaints. Therefore, the authors carried out aretrospective study to investigate the effect of breast-reducing surgery on neck pain and quality of life.

Between January1, 2014 and December31, 2019, 107 breast reductions were performed for macromastia. Medical records and OP reports were evaluated, and the indication for breast reduction documented. Pain was recorded preoperatively on avisual analog scale (VAS). Pretreatments and perioperative complications were also documented and evaluated. All patients were sent aquestionnaire, which determined whether the objective of the operation had been achieved, how satisfied the patients were with the result of the operation, and how severe the current pain (VAS) was. The EQ-5D3L health questionnaire was used to assess quality of life, and the Neck-Disabt reduction surgery is performed in patients with macromastia. A high patient satisfaction rate can be achieved and orthopedic clinical complaints associated with macromastia can be treated with a very high success rate.This study examined the association and level of agreement between criterion methods and the Apple Watch 4® and Fitbit Charge 3® for recording step count and heart rate when exercising in water on an aquatic treadmill (ATM). Sixteen healthy participants (13 females and 3 males) volunteered to take part in this study. Participants were submerged in an ATM pool to the level of their xiphoid process and completed 3-min exercise bouts at intensities that corresponded to a comfortable walk, brisk walk, jog, and running. A Polar® T31 chest strap recorded heart rate (HR) and a high-definition digital camera was utilized for recording step count (SC). Significant associations (p  less then  0.001) were observed between criterion methods and the Apple® (HR R2 = 0.99 and SC R2 = 0.87) and Fitbit® (HR R2 = 0.72 and SC R2 = 0.83) devices. The mean absolute error and relative error (%) for recording step count were 19.8 (7.4%) in the Apple Watch and 21.4 (8.5%) in the Fitbit and 0.90 (0.76%) in the Apple Watch and 4.2 (3.0%) in the Fitbit for recording heart rate. Both devices displayed a reasonable level of agreement for recording step count and heart rate when exercising in water. Linear regression analysis demonstrating the association between each wearable device and the Apple Watch and Fit Bit Charge for recording step count and heart rate.Brazil's Caatinga drylands is under extensive environmental deterioration, with 38% of its natural cover already lost. There is a need for a better understanding of the effects of such degradation on Caatinga's rich and singular biota. Bats form a large part of this biota, and are pointed as good bioindicators. Here, we used the micronucleus test -an easy-to-use, accessible and cost-effective in vivo approach- to detect DNA damage in cells from bats of different species and feeding habits in three protected areas in the Caatinga, comparing them with samples from an industrial sugarcane plantation. We hypothesized that environmental disturbance would reflect in DNA damage, with lower levels of damage in the less disturbed protected areas. The frequency of micronucleated cells differed significantly between sites and feeding habits (carnivores > insectivores > frugivores > nectarivores > hematophagous) but did not differ between sexes. Alarmingly, the highest levels of DNA damage were in two strictly protected areas (Seridó and Raso da Catarina Ecological Stations). Glossophaga and Anoura were the genera with more damaged cells, and had, respectively, 1.48 and 3.53 times more micronucleated cells (average of 19.33 and 22.67 cells, respectively) than individuals from the same genera from the area with least damaged cells (average of 7.80 and 5.00 cells, respectively). Our analysis is a warning call for an in-depth investigation on the effects of both genotoxic contamination and environmental stressors on bats and other species in Brazil's Caatinga, including the role that historical human-induced processes -like the intense use of agrochemicals- may have had in the region.This review reanalyses the data from four experiments originally designed to test the fragmentation hypothesis. Participants were asked to recall triple or quadruple associates, cued by each of their components in turn, and to guess if they could not remember. There were many errors in recall and many of those errors were repetitions of previous errors. This reanalysis focuses, not on the fragmentation hypothesis, but on the repetition of errors. It works backwards through sequences of test trials to discover the best prior match to the responses on each trial. It reports frequencies of different categories of repetition, conditional probabilities of repetition, correct recalls, and the probability of repetition in relation to the lag between trial and match in the test sequence. These results may be summarised as (1) every event (a stimulus or a response or just a retrieval) to which the participant attends is separately recorded in memory, creating an ordered record of those events that have engaged the participant's attention; (2) the compilation of the record is automatic; while attention to a stimulus is at the participant's disposal, the consequent entry into memory is not, and (3) the retrieval of a potential response from memory is spontaneous; that retrieval becomes an overt response if it is compatible with the cue. This makes sense of a number of historic anomalies in the study of recall and informs some contemporary problems in the study of short-term memory.Neuroendocrine neoplasms of the rectum (R-NENs) are rare; however, their incidence has increased almost threefold in the last few decades. Imaging of R-NENs includes two primary categories anatomic/morphologic imaging comprised of endoscopic ultrasound (EUS), computed tomography (CT), magnetic resonance imaging (MRI), and functional/molecular imaging comprising of planar scintigraphy, single-photon emission computed tomography (SPECT), and positron emission tomography (PET). The management depends on stage, dimension, atypical features, histological grade, and lymphovascular invasion (LVI). Low-risk local R-NENs can be resected endoscopically, and high-risk or locally advanced neoplasms can be treated with radical surgery and lymphadenectomy and/or chemoradiation. The review article focuses on imaging illustrations and discusses applications of different imaging modalities in diagnosing and managing R-NENs.The COVID-19 pandemic has strained the biological matrix supply chain. An upsurge in demand driven by numerous COVID-19 therapeutic and vaccine development programs to combat the pandemic, along with logistical challenges sourcing and transporting matrix, has led to increased lead times for multiple matrices. Biological matrix shortages can potentially cause significant delays in drug development programs across the pharmaceutical and biotechnology industry. Given the current circumstances, discussion is warranted around what will likely be increased use of surrogate matrices in support of pharmacokinetic (PK), immunogenicity, and biomarker assays for regulatory filings. Regulatory authorities permit the use of surrogate matrix in bioanalytical methods in instances where matrix is rare or difficult to obtain, as long as the surrogate is appropriately selected and scientifically justified. Herein, the scientific justification and possible regulatory implications of employing surrogate matrix in PK, immunogenicity, and biomarker assays are discussed. In addition, the unique challenges that cell and gene therapy (C>) and other innovative therapeutic modalities place on matrix supply chains are outlined. Matrix suppliers and contract research organizations (CROs) are actively implementing mitigation strategies to alleviate the current strain on the matrix supply chain and better prepare the industry for any future unexpected strains. To maintain ethical standards, these mitigation strategies include projecting matrix needs with suppliers at least 6 months in advance and writing or updating study protocols to allow for additional matrix draws from study subjects and/or re-purposing of subject matrix from one drug development program to another.
