ABSTRACT Background: An increase in fat accumulation in obesity has been suggested to link with an increase in inflammation. This inflammation may be associated with an elevated of Lipoprotein-Associated Phospholipase A2 (Lp-PLA2), Apolipoprotein B (Apo B), and Low-Density Lipoprotein (LDL), thereby associated with the risk of atherosclerosis.Objective: To investigate the differences between Lp-PLA2, Apo B, and LDL levels in obese and lean men.Methods: A cross-sectional study was conducted on 74 men (obese and lean) at the Faculty of Medicine, Diponegoro University, Indonesia, in 2020. The concentration of LDL was measured using the homogenous enzymatic colourimetric method, whereas the levels of Lp-PLA2 and Apo B were determined using the ELISA method. Data were analyzed using an Independent t-test, setting statistical significance at p <0.05.Results: This study showed that Lp-PLA2 levels were significantly different between obese and lean men (p = 0.039). Furthermore, LDL levels were also significantly different between obese and lean men (p = 0.002). However, we did not find any differences in Apo B between obese and lean men (p = 0.640).Conclusion: Lp-PLA2 and LDL levels were slightly higher in obese compared to lean men, but no difference of Apo B.

Abstract: Lacto-ovo vegetarian is the most common type of vegetarians in society. This type of vegetarian does not consume fish and meats, except eggs, milk, and its products. Apolipoprotein is a protein component of lipoprotein. Plasma lipoprotein is a complex macromolecule with a spherical form consists of specific lipid and protein. Apolipoprotein B (APO-B) is a main apolipoprotein in low density lipoprotein (LDL). It is also found in very low density lipoprotein (VLDL) and chylomicron. This study was aimed to obtain the description of serum apolipoprotein B (APO-B) levels in lacto-ovo vegetarians. This was a descriptive study with a cross sectional design. There were 15 respondents from Vihara Mandalatama Matreiya Manado obtained by using total sampling method. The results showed that 8 respondents (53.3%) had normal serum APO-B levels, 4 respondents (26.6%) had low serum APO-B levels, and 3 respondents (20%) had high serum APO-B levels. Conclusion: The majority of lacto-ovo vegetarians had normal levels of serum apolipoprotein B.Keywords: apolipoprotein B (APO-B), lacto-ovo vegetarian Abstrak: Vegetarian lacto-ovo merupakan jenis vegetarian yang paling umum di masyarakat.

ObjectivesSmall dense low-density lipoprotein cholesterol (sdLDL-C) might be a better cardiovascular disease (CVD) indicator than low-density lipoprotein cholesterol (LDL-C); however, details regarding its epidemiology remain elusive. The present study aimed at evaluating the association between the demographic factors, such as age, gender and menopausal status, and sdLDL-C levels and sdLDL-C/LDL-C ratio in the Japanese population.DesignThis was a cross-sectional study.Setting13 rural districts in Japan, 2010–2017.ParticipantsThis study included 5208 participants (2397 men and 2811 women), who underwent the health mass screening that was conducted in accordance with the medical care system for the elderly and obtained informed consent for this study.ResultsIn total, 517 premenopausal women (mean age ±SD, 45.1±4.2 years), 2294 postmenopausal women (66.5±8.8 years) and 2397 men (64.1±11.2 years) were analysed. In men, the sdLDL-C levels and sdLDL-C/LDL-C ratio increased during younger adulthood, peaked (36.4 mg/dL, 0.35) at 50–54 years, and then decreased. In women, relatively regular increasing trends of sdLDL-C level and sdLDL-C/LDL-C ratio until approximately 65 years (32.7 mg/dL, 0.28), followed by a downward or pleated trend. Given the beta value of age, body mass index, fasting glucose and smoking and drinking status by multiple linear regression analysis, standardised sdLDL-C levels and sdLDL-C/LDL-C ratio in 50-year-old men, premenopausal women and postmenopausal women were 26.6, 22.7 and 27.4 mg/dL and 0.24, 0.15 and 0.23, respectively. The differences between premenopausal and postmenopausal women were significant (p<0.001).ConclusionsSdLDL-C and sdLDL-C/LDL-C ratios showed different distributions by age, gender and menopausal status. A subgroup-specific approach would be necessary to implement sdLDL-C for CVD prevention strategies, fully considering age-related trends, gender differences and menopausal status.

BACKGROUND Hypothyroidism is the second most common endocrinopathy next to diabetes mellitus (DM). Hypothyroidism is associated with increased cardiovascular mortality and morbidity. Cardiovascular complications are some of the most profound, reproducible and reversible clinical findings associated with thyroid disease1 . Hence this study was undertaken to assess the cardiac dysfunction among patients with hypothyroidism by electrocardiogram (ECG) and echocardiogram (ECHO) so as to provide a proper treatment guideline even among milder cases. METHODS This was a cross sectional study carried among 50 new patients of hypothyroidism who presented to Navodaya Hospital, Raichur during 2015 to 2017. They were clinically evaluated and underwent relevant investigations, including thyroid profile estimation, cardiac evaluation using ECG and 2D ECHO. RESULTS Most cases fell in the age group of 31 - 40 years. There was an overall female preponderance (76 %) over all age groups with mean age of 42.02 years. Goiter was found in 8 % of patients, bradycardia and hypertension was seen in 30 % and 22 % respectively. Central nervous system (CNS) examination revealed delayed ankle jerk in 40 % followed by hoarseness of voice in 38 % of patients. Lipid analysis showed increase of total cholesterol (TC), low density lipoprotein (LDL), very low-density lipoprotein (VLDL), triglycerides (TGL) and decrease of highdensity lipoprotein (HDL). Normal ECG was found in 26 % of patients. Bradycardia was most common finding seen in 30 % (15) of patients. 24 % (12) of patients exhibited low voltage complexes. While, 46 % cases showed normal ECHO findings. 24 % of cases presented with pericardial effusion. 18 % cases presented with diastolic dysfunction among which majority were mild. None of the cases had severe diastolic dysfunction. Only a meagre 10 % cases showed intraventricular septum (IVS) thickness. CONCLUSIONS Pericardial effusion was seen among 24 % of patients while diastolic dysfunction was seen in 18 % patients. Thus, any unexplained pericardial effusion should be screened for hypothyroidism. KEYWORDS Hypothyroidism, Cardiac Dysfunction, 2D ECHO, ECG, Thyroid Stimulating Hormone (TSH)

Abstract We produced 20 mouse monoclonal antibodies against human plasma low-density lipoprotein (LDL). Individually they failed to precipitate LDL in agarose gel by the double-immunodiffusion technique; collectively they did, or as few as two combined monoclonal antibodies could do so. To mimic polyclonal antibodies in determination of apolipoprotein B (apo B) by radial immunodiffusion, a combination of four particular monoclonal antibodies (clones A, B, C, and D) was necessary. We characterized these four clones with respect to temperature dependency, affinity, total binding to 125I-labeled LDL, and specificity to the different species of apolipoprotein B. Two monoclonal antibodies (B and C) bound 100% of 125I-labeled LDL; clones A and D bound 80% and 87%, respectively. All four clones bound maximally to LDL at 4 degrees C. The affinity constants for clones A, B, C, and D were 0.6, 2.1, 3.8, and 2.3 X 10(9) L/mol, respectively. By the Western blotting technique, the four monoclonal antibodies all reacted with the species B-100 and B-74 of apolipoprotein B, and to various degrees with B-48 and B-26. Radial immunodiffusion (chi) and direct enzyme-linked immunosorbent assay (y) with a mixture of the four monoclonal antibodies gave almost identical results for 70 patients: y = 0.921 chi-2.58; r = 0.933.

We have studied the structure of the totally delipidated polypeptide (apolipoprotein B [apo B]) present in low-density serum lipoprotein in detergent (n-dodecyl octaethyleneglycol monoether) solution by electron microscopy. The protein-detergent complex appears as a rod-shaped particle, 75-80 nm long and 4.5-5.5 nm wide. The volume of this particle is consistent with the previously published composition reported by Watt and Reynolds (1980, Biochemistry 19:1593-1598) of two copies of apo B and five to six equivalent micelles of detergent. The asymmetric particle possesses a high degree of flexibility and a strong tendency to self-associate in an orderly fashion. The extent of this association is pH dependent.
