ABSTRACT: Blood samples were collected from randomly selected healthy Jabal Akhdar breed goats reared in two sites in the Jabal Akhdar region of Oman. Seven  males and 65 female goats, age range 2 months to 4 years, raised in Shnoot Al-Dar village were kept under a semi-intensive system (SIS) and 2 males and 18 females, age range 4 months to 5 years, raised in Al-Ala'lana village and kept the under free range system (FRS) were studied. Serum Cu and haematological values were measured. There were no significant (p>0.05) effects of age, sex or serum copper levels on the haematology of goats, so data was pooled and only the effects of the management system on serum Cu and haematology were analysed. There were highly significant (p<0.001) differences between the two systems in all parameters studied. FRS goats were higher than SIS goats in mean values (± SE) of serum Cu (mg/l) 0.60 ± 0.07 vs 0.48 ± 0.33, red blood cells (RBC) (X1012/L) value 15.03 ± 0.42 vs 14.97 ± 0.25, mean cell volume (MCV) (fl) 21 ± 21 vs 19.57 ± 0.19, and haematocrit (HCT) (%) value 31.84 ± 0.59 vs 29.6 ± 0.35.  SIS values were higher than FRS in haemoglobin (Hb) (g/dl) 9.34 ± 0.16 vs 9.26 ± 0.27, mean cell haemoglobin (MCH) (pg) 6.21 ± 0.05 vs 6.16 ± 0.08 and mean cell haemoglobin concentration (MCHC) (g/dl) 31.96 ± 0.38 vs 29.05 ± 0.64. Therefore, it is evident that the management system can affect the serum copper levels and haematology of the Jabal Akhdar breed of goats in the Jabal Akhdar region of Oman.

<b><i>Introduction:</i></b> The association of serum copper with polycystic ovarian syndrome (PCOS) has been studied for years, but no definite conclusion is drawn. Therefore, we conducted a meta-analysis to investigate serum copper concentrations in PCOS subjects compared with healthy controls. <b><i>Methods:</i></b> Electronic search was performed in PubMed, Google Scholar, and Scopus up to June 30, 2020, without any restriction. Standardized mean differences (SMDs) with corresponding 95% CIs in serum copper levels were employed with random-effects model. <i>I</i><sup>2</sup> was applied to evaluate heterogeneity among studies. <b><i>Results:</i></b> Nine studies, measuring plasma copper levels in 1,168 PCOS patients and 1,106 controls, were included. Pooled effect size suggested serum copper level was significantly higher in women with PCOS (SMD = 0.51 μg/mL, 95% CI = [0.30, 0.72], <i>p</i> &#x3c; 0.0001). The overall heterogeneity was not connected with subgroups of the country, but derived from the opposite result of 1 study. <b><i>Conclusion:</i></b> Our research generally indicated circulating copper level in PCOS sufferers was significantly higher than normal controls. Large-scale studies are still needed to elucidate the clear relation between copper status and etiology of PCOS.

The study was designed to explore serum copper as a risk factor for coronary artery disease (CAD). In this case-control study 30 healthy controls and 60 diagnosed cases of acute myocardial infarction (AMI) were enrolled. Serum copper concentration and serum lipid profile were measured in all study subjects. Serum copper level was significantly higher in AMI as compared to controls. The concentrations of serum TC, TG, LDL-C level were found to be significantly higher in cases as compared to controls. The concentration serum HDL-C was found to be significantly lower in cases as compared to controls. CAD leads to raised serum copper level and it has positive correlation with TC, TG and LDL-C but negative correlation with HDL-C in males.Keywords: Coronary artery disease; serum copper; acute myocardial infarction; total cholesterol; triglyceride; low density lipoprotein cholesterol.

Background: Altered copper levels have been observed in several cancers, but studies on the relationship between serum copper and early-stage triple-negative breast cancer (TNBC) remain scare. We sought to establish a predictive model incorporating serum copper levels for individualized survival predictions.Methods: We retrospectively analyzed clinicopathological information and baseline peripheric blood samples of patients diagnosed with early-stage TNBC between September 2005 and October 2016 at Sun Yat-sen University Cancer Center. The optimal cut-off point of serum copper level was determined using maximally selected log-rank statistics. Kaplan-Meier curves were used to estimate survival probabilities. Independent prognostic indicators associated with survival were identified using multivariate Cox regression analysis, and subsequently, prognostic nomograms were established to predict individualized disease-free survival (DFS) and overall survival (OS). The nomograms were validated in a separate cohort of 86 patients from the original randomized clinical trial SYSUCC-001 (SYSUCC-001 cohort).Results: 350 patients were eligible in this study, including 264 in the training cohort and 86 in the SYSUCC-001 cohort. An optimal cut-off value of 21.3 μmol/L of serum copper was determined to maximally divide patients into low- and high-copper groups. After a median follow-up of 87.1 months, patients with high copper levels had significantly worse DFS (p = 0.002) and OS (p &lt; 0.001) than those with low copper levels in the training cohort. Multivariate Cox regression analysis revealed that serum copper level was an independent factor for DFS and OS. Further, prognostic models based on serum copper were established for individualized predictions. These models showed excellent discrimination [C-index for DFS: 0.689, 95% confidence interval (CI): 0.621–0.757; C-index for OS: 0.728, 95% CI: 0.654–0.802] and predictive calibration, and were validated in the SYSUCC-001 cohort.Conclusion: Serum copper level is a potential predictive biomarker for patients with early-stage TNBC. Predictive nomograms based on serum copper might be served as a practical tool for individualized prognostication.

Background: Tuberculosis is a major public health concern throughout the world including Bangladesh. The prevalence of tuberculosis (TB) is increasing day by day. Around one-third of world population is infected with M. tuberculosis. Still pulmonary tuberculosis (PTB) remains one of the important causes of mortality throughout the world with economic burden. Objective: To evaluate levels of the serum zinc and serum copper in smear positive PTB patients before starting Directly Observed Treatment, Short-course (DOTs) therapy. Methods: This was a cross-sectional type of observational study. A total of 100 subjects were included in this study. Among them 50 were smear positive PTB patients denoted as case group and 50 were apparently healthy individuals denoted as control group. Biochemical tests were carried out in the department of biochemistry of Mymensingh Medical College, Mymensingh. All the statistical analyses were performed by using SPSS version 21. Results were evaluated by using Student’s t-test. Results: After careful evaluation there was significant decrease in serum zinc level along with significant increase in serum copper level among the case group when compared with the control group. The mean values of serum zinc level were 93.96±10.04 μg/dl and 72.84±7.73 μg/dl in control and case group respectively. Serum zinc level decreased significantly (p <0.001) in PTB patients. The mean values of serum copper were 111.81±21.26 μg/dl and 125.99±27.93 μg/dl in control and case group respectively. There was significant (p <0.001) rise of serum copper level in PTB patients.

Background: Epilepsy is a central nervous system disorder in which brain activity becomes irregular, causing seizures or periods of unusual behavior, sensations, and sometimes loss of awareness. Serum copper level may change due to long term use of antiepileptic drugs. Objective: The purpose of the present study was to assess the serum copper level in childhood epilepsy treated with long-term Anti-Epileptic Drug (AED). Methodology: This cross-sectional study was carried out in the Department of Paediatric Neurology, Bangabandhu Sheikh Mujib Medical University (BSMMU) during March to August’ 2013. Sample size was one hundred, among these fifty were case (epileptic child who had received  anti-epileptic drugs (Carbamazepine and/or Valproic acid) for more than three months) and rest fifty were control (newly diagnosed epileptic child, who yet not received antiepileptic drug). Result: The mean copper level was 1.11±0.32 µg/ml in case group and 0.96±0.20 µg/ml in control group, which was statistically significant (p<0.05). Conclusion: The use of one drug or multiple drugs in the treatment of epileptic patients may play significant role in increasing copper serum level.

The effect of turpentine, estradiol benzoate and epinephrine hydrochloride on the copper concentration and paraphenylenediamine oxidase activity of serum were studied in the male albino rat. All three of these substances raised the serum copper level and paraphenylenediamine oxidase activity in both ‘control’ and ‘adrenalectomized’ animals, turpentine being the most active. The average serum copper level is approximately the same for normal humans and rats, while the phenylenediamine oxidase activity of normal human serum is about 2–3 times as high as that of rat serum. The data are discussed with relation to the known facts about serum copper in normal subjects and mental patients.
