“…We can associate this difference which is related to sex as hormonal change in the women during pregnancy, since during pregnancy and hormonal increase normal level of blood cholesterol is observed just after parturition and within or during menstrual period [14]. Our ratio of male to female was (1: 3.3), which is different from the ratios of Mexican Americans and Pima Indians respectively (1:5.3) & (1:16.6) [15].…”

Objective: The aim of this study was to determine the occurrence of cholelithiasis in the city of Lahore and its surrounding area. Material and Methods: This study was conducted at Shalamar Medical and dental college Lahore and data for this study was collected from different hospitals of Lahore and the duration of this study was from 2019 to 2021. The participants of this study were from both genders’ male and female from of the age of 10 years to 80 years, and the sample size for this study was 483 and 1583. The main focus of our study was to examine the occurrence of Cholelithiasis surgical in the duration of our study. A questionnaire was used to analyses the occurrence of gall stone, and also the sex, age and dietary habits of the patients. Results: In the results of this study the frequency of gall stones were observed 4.0% in males and 12.0% in females and the percentage of occurrence of gall stones in both these genders were 1% to 3.3%. the high occurrence rate of gall stones in the months are May and November, in both these months the observation of gall stones in these were very high. Both the genders were divided into two main age groups in which male age group were from 10 years to 78 years and the females age group were from 11 years to 80 years. The ideal age for the occurrence of gall stones in male were 45 years to 59 years and in females were 3 years to 44 years respectively. Conclusions: In the conclusion of this study, we examine that the overall occurrence of gall stones in both the genders were 7.01%, but at same the time occurrence rate in the females were very high as compared to the male which were 1% in males and 3.3% in females. Keywords: Cholelithiasis, Surgical Incidence, Gallstones.

“…On the other hand, to enhance the quantitative analysis of samples, the accumulating energy of laser radiation and laser shots is usually used to get better signal intensity [27] and reduce signal fluctuations from pulse to pulse [28] during measurements. Herein, the relative standard deviation (RSD) of the measurements performed under the same experimental conditions was calculated from seven replicated values [29].…”

In this work, laser-induced breakdown spectroscopy (LIBS) analysis is optimized for direct estimation of elemental composition, thermal conductivity and hardness for Ni-Cr-Nb alloys. These alloys were chosen with a variable elemental content of niobium and chromium. The influence of laser energy and shot numbers on measuring line intensity was investigated. Based on the ratio between two spectral lines, calibration curves were formed to estimate the element concentration and LIBS results were confirmed with related energy-dispersive X-ray spectroscopy (EDS) data. Hardness and thermal conductivity estimation using LIBS were done by measuring the ratio between two spectral lines, plasma excitation temperature and electron density for different samples. Semi-empirical formulas correlated hardness and thermal conductivity with plasma temperature were established.

“…However, the detection of heavy metals is a complicated procedure, often involving widespread processes of preparation of sample leading to the measurement, when analytical techniques are employed [15]. Such standard techniques for the detection of heavy metal ions such as inductively coupled plasma optical emission spectrometry (ICP-OES) [16][17][18], UV-Vis spectrometry, [19][20][21] atomic absorption/emission spectroscopy [22][23][24] and laser-induced breakdown spectroscopy (LIBS) [25,26], would not be suitable for in situ, fast, easy and low-cost operation.…”

The need for constant assessment of river water qualities for both aquatic and other biological survival has emerged a top priority, due to increasing exposure to industrial pollutants. A disposable screen print carbon electrode was modified with a conductive polymer (PANI) and Zn and/or Cu oxides NPs, obtained through bioreduction in citrus peel extracts (lemon and orange), for ultra-sensitive detection of PB2+, in the Crocodile River water sample. The synthesized materials were characterized with Fourier-transform infra-red spectroscopy (FTIR), ultra-violet visible spectroscopy (UV-Vis), and scanning electron microscopy (SEM). The SPC-modified electrodes designated as SPCE/LPE/BiONPs/PANI and SPCE/OPE/BiONPs/PANI were characterized using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) and eventually deployed in the electrochemical detection of PB2+ in water using square wave voltammetry (SWV) technique. The electrochemical responses of the modified electrodes for both CV and EIS in 0.1 M HCl demonstrated enhanced performance relative to the bare SPCE. A detection and quantification limit of 0.494 ppb and 1.647 were obtained at SPCE/LPE/BiONPs/PANI, respectively, while a detection and quantification limit of 2.79 ppb and 8.91 ppb, respectively, were derived from SPCE/OPE/BiONPs/PANI. The relative standard deviations (RSD) for SPC electrode at a 6.04 µM PB2+ analyte concentration was 4.76% and 0.98% at SPCE/LPE/BiONPs/PANI and SPCE/LPE/BiONPs/PANI, respectively. The effect of copper, zinc, iron, cobalt, nickel, and magnesium on the stripping peaks of PB2+ at SPCE/OPE/BiONPs/PANI, showed no significant change except for cobalt, with about 17.67% peak current drop. The sensors were assessed for possible determination of PB2+ in spiked river water samples. The average percentage recovery and RSD calculated were 94.25% and 3.74% (n = 3) at SPCE/LPE/BiONPs/PANI and, 96.70% and 3.71% (n = 3) at SPCE/OPE/BiONPs/PANI, respectively. Therefore, the fabricated sensor material could be used for environmental assessment of this highly toxic heavy metal in the aquatic system
