“…Since osteoporotic fractures impose a huge social and economic burden, enormous effort has been undertaken to manage this problem, particularly the development of viable preventive and therapeutic approaches for osteoporosis. Advanced age [121], sex hormone deficiency [122], the use of medication [123], alcohol consumption [124], smoking [125], as well as underlying medical complications such as hypertension [126], diabetes [127], hyperlipidemia [128] and MetS [129][130][131] are the common contributing factors for poor bone health.…”

Tocotrienol (T3) is a subfamily of vitamin E known for its wide array of medicinal properties. This review aimed to summarize the health benefits of T3, particularly in prevention or treatment of non-communicable diseases (NCDs), including cardiovascular, musculoskeletal, metabolic, gastric, and skin disorders, as well as cancers. Studies showed that T3 could prevent various NCDs, by suppressing 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) in the mevalonate pathway, inflammatory response, oxidative stress, and alternating hormones. The efficacy of T3 in preventing/treating these NCDs is similar or greater compared to tocopherol (TF). TF may lower the efficacy of T3 because the efficacy of the combination of TF and T3 was lower than T3 alone in some studies. Data investigating the effects of T3 on osteoporosis, arthritis, and peptic ulcers in human are limited. The positive outcomes of T3 treatment obtained from the preclinical studies warrant further validation from clinical trials.Nutrients 2020, 12, 259 2 of 84 Nutrients 2020, 12, 259 4 of 84 the order δ > γ > β > α [45]. Using HepG2 cells, γT3 was shown to stimulate apolipoprotein B (Apo-B) degradation by decreasing its translocation into the endoplasmic reticulum (ER) lumen. This action eventually caused a reduction in the number of Apo-B in lipoprotein particles [46]. Other reports showed that γT3 and δT3 had the potential to reduce the hepatic TG synthesis and very-low-density lipoprotein (VLDL) secretion by suppressing expression of genes involved in lipid homeostasis, particularly the TG, cholesterol, and VLDL biosynthesis. Moreover, δT3 also promoted the efflux of LDL through LDL receptor expression [47]. A summary of the literature on effect of T3 supplementation on lipid profile of hypercholesterolemic model in vitro is shown in Table 1.Animal models of dyslipidemia have been used to investigate the effects of T3 on lipid profile. Several animals have been tested, including chicken, swine and rodents (rats, hamsters, guinea pigs). In chickens fed with a varying level of αTF and γT3, Qureshi et al. (1996) showed that αTF enhanced the inhibition of HMGCR by γT3. They further stipulated that the vitamin E mixture should contain 15-20% of αTF and approximately 60% of γT3 or δT3 for optimal anti-cholesterol effects [48]. In the subsequent study, demonstrated that combination of 50 ppm T3-rich fraction (TRF) and 50 ppm lovastatin was more effective in suppressing HMGCR activity compared to lovastatin alone in chickens. The combination also reduced serum TC and LDL-C, TG, Apo-B, thromboxane B 2 , and platelet factor 4 in contrast to individual treatment [49]. Using chicken supplemented with 50 ppm of δT3, Qureshi et al. (2011) further revealed that δT3 reduced TC and LDL-C besides suppressing the lipid elevating effects of dexamethasone and potentiated the TG-lowering effect of riboflavin [50]. Using genetically hypercholesterolemic swine, Qureshi et al. (1991) demonstrated the significant effect of TRF in lowering serum TC, LDL-C, Apo-B, thrombo...

“…Metabolic syndrome (MetS) is defined as a constellation of risk factors which predisposes an individual to other medical complications, such as cardiovascular disease [1,2], type II diabetes [3], cancer [4][5][6], non-alcoholic fatty liver disease [7], and bone loss [8][9][10]. The risk factors of MetS include abdominal obesity, hyperglycemia, hypertension, high triglycerides, and low high-density lipoprotein (HDL) cholesterol.…”

Metabolic syndrome is a cluster of metabolic abnormalities including central obesity, hyperglycemia, hypertension, and dyslipidemia. A previous study has established that high-carbohydrate high-fat diet (HCHF) can induce MetS in rats. In this study, we modified components of the diet so that it resembled the diet of Southeast Asians. This study aimed to determine the effects of this modified HCHF diet on metabolic parameters in rats. Male Wistar rats (n=14) were randomised into two groups. The normal group was given standard rat chow. The MetS group was given the HCHF diet, comprises of fructose, sweetened condensed milk, ghee, Hubble Mendel and Wakeman salt mixture, and powdered rat food. The diet regimen was assigned for a period of 16 weeks. Metabolic syndrome parameters (abdominal circumference, blood glucose, blood pressure, and lipid profile) were measured at week 0, 8, 12, and 16 of the study. The measurement of whole body composition (fat mass, lean mass, and percentage of fat) was performed using dual-energy X-ray absorptiometry at week 0, 8, and 16. Our results indicated that the components of MetS were partially developed after 8 weeks of HCHF diet. Systolic blood pressure, triglyceride, low density lipoprotein cholesterol, fat content, and percentage of fat was significantly higher in the HCHF group compared to normal group (p<0.05). After 12 weeks of HCHF diet, the rats showed significant increases in abdominal circumference, blood pressure, glucose intolerance, and dyslipidemia compared to normal control (p<0.05). In conclusion, MetS is successfully established in male rats induced by the modified HCHF diet after 12 weeks.

“…In addition, Wilson et al (17) utilised a retrospective analysis of clinical patients aged 10-89 years with chronic renal disease, intestinal failure, anorexia, malnutrition, obesity, liver disease, metabolic disorders and others, whereas the present study sample consisted of apparently healthy Hispanic adults 18-45 years of age. It is commonly understood that conditions such as anorexia (45) , malnutrition (46,47) and metabolic disorders (48) negatively impact bone health. As such, equations derived from a sample of clinical patients may be inaccurate when applied to the general population.…”

Development of a dual-energy X-ray absorptiometry-derived body volume equation in Hispanic adults for administering a four-compartment model

The purpose of the present study was: (1) to develop a new dual-energy X-ray absorptiometry (DXA)-derived body volume (BV) equation with the GE-Lunar prodigy while utilising underwater weighing (UWW) as a criterion and (2) to cross-validate the novel DXA-derived BV equation (4C-DXANickerson), Wilson DXA-derived BV equation (4C-DXAWilson) and air displacement plethysmography (ADP)-derived BV (4C-ADP) in Hispanic adults. A total of 191 Hispanic adults (18–45 years) participated in the present study. The development sample consisted of 120 females and males (50 % females), whereas the cross-validation sample comprised of forty-one females and thirty males (n 71). Criterion body fat percentage (BF %) and fat-free mass (FFM) were determined using a four-compartment (4C) model with UWW as a criterion for BV (4C-UWW). 4C-DXANickerson, 4C-DXAWilson and 4C-ADP were compared against 4C-UWW in the cross-validation sample. 4C-DXANickerson, 4C-DXAWilson and 4C-ADP all produced similar validity statistics when compared with 4C-UWW in Hispanic males (all P > 0·05). 4C-DXANickerson also yielded similar BF % and FFM values as 4C-UWW when evaluating the mean differences (constant error (CE)) in Hispanic females (CE = –0·79 % and 0·38 kg; P = 0·060 and 0·174, respectively). However, 4C-DXAWilson produced significantly different BF % and FFM values (CE = 3·22 % and –2·20 kg, respectively; both P < 0·001). Additionally, 4C-DXAWilson yielded significant proportional bias when estimating BF % (P < 0·001), whereas 4C-ADP produced significant proportional bias for BF % and FFM (both P < 0·05) when evaluated in Hispanic females. The present study findings demonstrate that 4C-DXANickerson is a valid measure of BV in Hispanics and is recommended for use in clinics, where DXA is the main body composition assessment technique.
