A population analysis was made using data of the grunt Pomadasys panamensis. The information is from the catch from 260 hauls in estuarine waters, open-ocean waters, and off the coast of Sinaloa and northern Nayarit, Mexico, in the southeastern Gulf of California. The area of influence is about 120,000 km2 and includes about a third of the drag area of the largest shrimp fleet of the American Pacific. The average length in the population was 210 mm. The maximum length was 430 mm and the minimum was 50 mm. The analysis for the frequency distributions of the lengths and the multinomial solution produced representative modal groups for 160 mm, 190 mm, and 230 mm. The simulation of the biomass density gave an estimate close to 90 t, with 650,000 organisms before starting the fishing season in the region. The density was 0.19 kg ha–1. The colonization was 0.42% or 42 %. The model was validated using the Aikaikae criterion (AIC). The results provide an overview of the initial biomass densities and population structure of the species caught as bycatch, demonstrating the importance of this species abundance in the shrimp fishery, and generating a source of monetary income to the crew of the fishing fleet. The persistence of the species to fishing provides an example to study the mechanisms of survival.

This paper is devoted to a study of geometric properties of ar(q) nonlinear regression models. We present geometric frameworks for regression parameter space and autoregression parameter space respectively based on the weighted inner product by fisher information matrix. Several geometric properties related to statistical curvatures are given for the models. The results of this paper extended the work of Bates & Watts(1980,1988)[1.2] and Seber & Wild (1989)[3].

Background: Eyes are one of the most important facial features, their appearance being associated with state of mind, age and beauty. Therefore, upper blepharoplasty is one of the most common procedures performed in plastic surgery. Standardized tools allow for measurement of outcomes through patient satisfaction and surgeon experience. Objectives: Our objective was to measure the satisfaction index and scar quality of patients who underwent upper blepharoplasty using the Patient-reported Outcome Measure Questionnaire (PROM-Q) and Patient and Observer Scar Assessment Scale (POSAS). Methods: A retrospective review of patients that underwent upper blepharoplasty in our institution was performed. We included those with a preoperative anthropometric analysis, standardized incision markings (developed in our center), same operative technique and a 3-month postoperative evaluation with PROM-Q and POSAS. The sample for this study consists of 67 patients, all of them operated between January 1 2019 and June 30 2019 at the Department of Plastic Surgery, South Central High Specialty Hospital, Pemex, Mexico City, Mexico. Results: A total of 67 patients were included, 73% female and 27% male. The most frequent indication for surgery was functional visual symptoms. The index of PROM-Q at 3 months demonstrated an increased satisfaction above 90%, and the evaluation with POSAS reported an almost imperceptible scar. Conclusion: Evaluating outcomes with objective tools provides data useful to improve the surgical protocols of patients subjecting to aesthetic procedures.

A 1.8 kg, seven months old, intact, female, mix-breed cat was referred with dyspnea and paresis. Since the patient was in such a condition that she was too incapable of the operation, treatment for dyspnea was performed. The patient has abdominal enlargement. When the respiratory stress of the patient decreased, a radiograph was taken and lordosis was found. Medical treatment was applied, because the general condition was impaired. Lordosis is the excessive curvature of a certain number of vertebrae in the neck and back region. Congenital thoracic lordosis has been described as a highly progressive and low vital capacity disease in humans and cats. Because it compresses the lung, it can cause dyspnea in patients and rhythm disturbances in the heart. This case represents a severe example of untreatable and unmanageable lordosis encountered in a cat.
