Application of Proteomics in Alzheimer’s Disease: A Mini Review

@#Alzheimer’s disease (AD) is classified as one of neurodegenerative disease caused by neuronal death. It is characterized as memory impairment, including the inability to produce new memories. Since AD has low treatment effectiveness, proteomics research opens possibilities for advancement. Proteomics is the study of proteomes produced by the disease-bearing host to identify and understand diseases. In this case, to investigate the use of protein as a reliable molecular entity and their involvement in AD. Therefore, this review focused on three main applications of proteomics; the potential use of proteomics as a diagnostic tool for AD, the use of proteomics to assess the treatment progression of AD and the advancement in AD research. The review discussed three research areas utilizing the proteomics approach: ageing, behavioural, and demographic research of AD populations. Proteomic approaches have also been shown to be effective to discover the biomarkers for infectious diseases, cancers, heart diseases, and neurological disorders. Although much work remained to be done, the proteomics approach is an interesting method to be carried out in detecting AD at an earlier stage and will be very useful for AD treatment and management in the future.

Diastolic dysfunction grading, echocardiographic and electrocardiogram findings in 50 patients with apical hypertrophic cardiomyopathy

@#Introduction: Apical Hypertrophic Cardiomyopathy (Apical HCM) is an uncommon variant of hypertrophic cardiomyopathy, but it is relatively more common in Asian countries. This is a retrospective, non-randomised, single centre study of patients with Apical HCM focusing on their diastolic dysfunction grading, echocardiographic parameters and electrocardiograms (ECG). Methods: All Apical HCM patients coming for clinic visits at the Institut Jantung Negara from September 2017 to September 2018 were included. We assessed their echocardiography images, grade their diastolic function and reviewed their ECG on presentation. Results: Fifty patient were included, 82% (n=41) were males and 18% (n=9) females. The diastolic function grading of 37 (74%) patients were able to be determined using the updated 2016 American Society of Echocardiography (ASE) diastolic guidelines. Fifty percent (n=25) had the typical ace-ofspades shape left ventricle (LV) appearance in diastole and 12% (n=6) had apical pouch. All patients had T inversion in the anterior leads of their ECG, and only 52% (n=26) fulfilled the ECG left ventricular hypertrophy (LVH) criteria. Majority of our patients presented with symptoms of chest pain (52%, n=26) and dyspnoea (42%, n=21). Conclusion: The updated 2016 ASE guideline makes it easier to evaluate LV diastolic function in most patients with Apical HCM. It also helps in elucidating the aetiology of dyspnoea, based on left atrial pressure. Clinicians should have a high index of suspicion for Apical HCM when faced with deep T inversion on ECG, in addition to a thick LV apex with an aceof-spades appearance during diastole.

Ameliorative Effects of Aquilaria malaccensis Leaves Aqueous Extract on Reproductive Toxicity Induced by Cyclophosphamide in Male Rats

@#Background: Cyclophosphamide (CP) is a widely used anti-neoplastic and immunosuppressive agent that is associated with adverse side effects including reproductive toxicity. Aquilaria malaccensis (AM) is a traditional medicinal plant which was reported to exhibit high anti-oxidant and free radical scavenging properties. The present study was aimed to evaluate the protective effects of AM leaves extract on sperm quality following toxic exposure to CP. Methods: Forty-eight male Sprague Dawley rats were allocated into eight groups of six rats (n = 6): control, CP only (200 mg kg−1), AM only (100 mg kg−1, 300 mg kg−1 and 500 mg kg−1) and CP + AM (100 mg kg−1, 300 mg kg−1 and 500 mg kg−1). Animals were sacrificed after 63 days of treatment and the sperm from the caudal epididymis was taken for sperm analysis. Results: The body and the reproductive organs weight, sperm count and motility did not differ between CP and other groups (P > 0.05). A significant increase (P < 0.05) in percentage of the dead and abnormal sperm were seen in the CP alone treated group compared to the control group. Co-administration of AM to the CP exposed rats significantly reduced the (P < 0.05) percentage of abnormal sperm as compared to the CP only group. Conclusion: Overall, the present results represent the potential of AM to protect against CP induced reproductive toxicity.

Cosmetic outcome of hypofractionated whole-breast irradiation with concomitant boost in breast cancer

Background: Breast cancer is the most common cancer in women worldwide, second most common malignancy in Egypt.Methods: 60 early-stage breast cancer patients who underwent breast-conserving surgery were clusterized into 2 groups: Arm A hypofractionation with concomitant boost and Arm B conventional fractionation, each compromising 30 early stage breast cancer patients. Assessment of cosmetic outcome after breast irradiation was recorded in both groups in 4 intervals to correlate cosmesis in relation to different irradiation schedules and boost dosage and timing. The study was conducted from April 2016 till December 2018, 32 months were obtained to assure that all patients completed their irradiation schedule and 12 months follow-up period.Results: Lowest cosmetic outcome was recorded immediately after completion of breast irradiation with excellent/good in 66.7% and 73.3% of patients and fair/poor in 33.3% and 26.7% in Arm A and B, respectively. Improvement in cosmesis after 12 months of breast irradiation reaching excellent/good in 83.4% and fair/poor in 16.7% in both Arm A and B.Conclusion: An abbreviated 4-week hypofractionated schedule with a concomitant boost is as effective as conventional irradiation with comparable cosmesis and may be a reasonable alternative following breast conserving surgery

Assessing groundwater stoichiometric composition and its suitability in Northwestern Bangladesh / Avaliação de lençol de água quanto a composição estioquiométrica e a sua conveniência do Noroeste do Bangladesh

Groundwater quality analyses included pH, EC, cations (Ca2+, Mg2+, Na+, K+, Zn2+, Cu2+, Mn2+, Fe3+ and As3+), anions (CO32-, HCO3-, NO3-, SO42-, PO43- and Cl-) and TDS of northwestern Bangladesh. The samples contained Ca2+, Mg2+ and Na+ as the dominant cations and HCO3- and Cl- were the dominant anions. Ratios of major cations and anions of water samples suggest the predominance of Ca and Mg-containing minerals over Na-containing minerals. According to TDS and SAR values, all samples were classed as 'freshwater' and 'excellent' categories. The SSP of all waters was under 'excellent' and 'good' classes. All samples were within 'soft' class regarding hardness with 'suitable' RSC.
