Abstract

The aim of this study was to investigate the influence of intermittent hypobaric hypoxia on the expression hypoxia adaptation proteins, namely hypoxia inducibla factor-1a (HIF-1a) and myoglobin (Mb). Twenty five male Sprague-Dawley rats were exposed to intermittent hypobaric hypoxia in a hypobaric chamber in Indonesian Air Force Institute of Aviation Medicine, for 49.5 minutes at various low pressure, 1 week interval for 4 times (day 1, 8, 15 and 22). HIF-1α and Mb protein were measured with ELISA. mRNA expression of Mb was measured with one step real time RT-PCR. HIF-1α protein levels increased after induction of hypobaric hypoxia and continues to decrease after induction of intermittent hypobaric hypoxia 3 times (ANOVA, p = 0.0437). mRNA expression and protein of Mb increased after induction of hypobaric hypoxia and continues to decrease after induction of intermittent hypobaric hypoxia 3 times (ANOVA, p = 0.0283; 0.0170), and both are strongly correlated (Pearson, r = 0.6307). The heart of rats adapted to intermittent hypoxia conditions by upregulation the expression of HIF-1a and myoglobin and then both return to normal level.

Abstract

Background: High altitude can cause hypobaric hypoxia (HH), resulted from the lower barometric pressure and hence partial pressure of oxygen. Hypoxia can lead to a lot of deleterious molecular and cellular changes, such as generation of free radicals or reactive oxygen species (ROS). Increasing of ROS can cause oxidative stress if the antioxidant enzyme does not increase simultaneously. Oxidative damage in brain has toxic effect on cognitive functions. Objective: In this study, we investigate effect of acute intermittent HH on oxidative stress and antioxidant enzyme activity in rat brain. Method: Wistar rats divided into 5 groups, consisting control group and four experimental groups which treated to HH. Rats were exposed to simulated HH equivalent to 35.000 feet in hypobaric chamber for 1 minute, repeated once a week. Results: Level of malondialdehyde and carbonyl in rat brain under acute HH increased at HH exposure (group I) compare to control group. These levels decreased afterward at intermittent HH exposure (group II-IV). Specific activity of superoxide dismutase (SOD) shows increasing level at intermittent HH exposure, especially group IV was increasing of SOD level significantly. The increasing pattern of specific activity of catalase was inversely from SOD pattern, but it still has higher activity in intermittent HH compare to control group. Conclusion: Brain tissue seems to be able to perform an adequate adaptive response to hypobaric hypoxia after the training, shown by its significantly decreased MDA and carbonyl level and also increased specific activity of SOD and catalase.

Abstract

Background: Following surgical treatments for low back pain, lower extremity pain or neurologic symptoms would last or recur, this is defined as failed sack surgery syndrome (FBSS). FBSS usually occurs in 5-40% of these surgical patients. The most common cause is an epidural scar adhesion. Percutaneous epidural neuroplasty is the non-mechanical treatment for this condition. Previously, the use of hyaluronidase and hypertonic saline separately is commonly used for epidurolysis but the combination of hyaluronidase and hypertonic saline 3% has not been explored.Objective: To investigate the two-year outcomes of percutaneous epidural neuroplasty using a combination of hyaluronidase and hypertonic saline 3% in patients with FBSS.Methods: Twelve patients who experience low back pain, with or without radiculopathy, who have underwent lumbar spine surgery previously were assigned to the study. Parameters, such as the visual analogue scale scores for the back (VAS-B) and legs (VAS-L), and the Oswestry disability index (ODI), were recorded and compared between pretreatment, 1 week, 1 month, 3 months, 1 year and 2 years follow-up.Results: For all 12 patients, the postoperative VAS-B, VAS-L, and ODI were significantly different from the preoperative values in all follow-up periods: 1 month, 3 months, 1 year, and 2 years.Conclusion: Based off this study group, percutaneous epidural neuroplasty using a combination of hyaluronidase and hypertonic saline 3% has a favourable outcome in the 2 years follow-up

Abstract

Introduction: Helicopter pilots are potentially at risk of Low Back Pain (LBP) and are twice as likely as fighter pilots to experience it. Helicopter pilots’ LBP is caused by a combination of risk factors: engine and rotor vibration, ergonomic risks due to cockpit design, static seating position due to operations, and individual factors. These factors are incorporated into cumulative aviation risk exposure, which can be measured by total flight hours. The prevalence of LBP in Caucasians is high, at 50.5%-92%. However, there has not been any research on Indonesian military helicopter pilots who have a different posture from Caucasians.Objective: To determine the prevalence of LBP, to analyze the relationship between total flight hours and individual factors (age, height, BMI, exercise habits, and smoking habits) with LBP in Indonesian military helicopter pilots.Methods: The study was conducted at the Indonesian Army and Indonesian Air Force with total sampling method as many as 124 people. An explanation was carried out followed by filling in the consent to become a research subject, filling in personal data, anamnesis, Numeric Rating Scale (NRS), physical examination, neurological examination, and total flight hour data.Results: There were 124 subjects, consisting of 37.9% pilots and 62.1% copilots, 87.9% of pilots operate large helicopters, have average total flight hours of 450 hours, age of 30 years, the height of 172.66 cm, low intensity exercise habits of 61.3%, and smokers as much as 45.2%. A total of 57 people (46%) experienced LBP. Statistical results showed that total flight hours had an association with LBP (p = 0.035) where each 1 unit increase in total flight hours had a 1.02 times greater chance of LBP.Conclusion: The prevalence of LBP is 46% and there is an association between total flying hours and LBP in Indonesian military helicopter pilots.

Abstract

Hypobaric hypoxia is situation that might occur to helicopter pilots in Indonesia who must fly at an altitude of more than 3,048 m such as in Papua. It can be dangerous because hypoxic condition can affect person's performance. So far, the heart is known as an aerobic organ and very sensitive to hypoxic conditions. Hitherto, the effects of hypobaric hypoxia exposure on biomolecular aspects of the heart are still unclear. Therefore, this study assessed cardiac response in rats exposed to intermittent hypobaric hypoxia (IHH) (equivalent to 3,048 meters/10,000 feet). Sprague-Dawley rats were divided into six groups: control; acute hypobaric hypoxia (AHH); and IHH, for 7; 14; 21; and 28 days. We measured super oxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) activities, reduced glutathione (GSH), malondialdehyde (MDA), cytoglobin, myoglobin, HIF-1α, and Nrf2 level as our parameters. Activities of SOD, CAT, GPx and GSH increased while the levels of MDA, cytoglobin, myoglobin, HIF-1α, and Nrf2 decreased in all IHH groups compared with the AHH group. A biphasic pattern was observed as IHH sessions increased from 14 to 21 or 28. Where the IHH treatment for more than 14 sessions caused a decrease in endogenous antioxidants, but the response to hypoxia and oxidative stress increased. Our findings presented the molecular alterations of cardiac rats exposed to intermittent hypobaric hypoxia.

Abstract

Many studies have reported that intermittent hypobaric hypoxia (IHH) can cause oxidative stress and tissue damage in the kidneys, which can lead to impaired kidney function. However, a study using simulated intermittent hypobaric hypoxia was considered to have a protective role for the kidneys. This study aims to determine the effect of IHH on kidney adaptation to oxidative stress and kidney damage. Twenty-five rats were divided into five groups: control, one-time hypoxia (AHH), two-time hypoxia (IHH 1), three-time hypoxia (IHH 2), and four-time hypoxia (IHH 3). The intermittent interval was one week, and at the time of treatment, the rats were placed in a hypoxic chamber. At the end of treatment, the rats were sacrificed, and the kidneys, urine, and blood were collected. The kidney tissues were used for protein assay, ELISA (HIF-1α and VEGF), qPCR (cytoglobin (Cygb) and renin), SOD and GPx activity assay. Blood was used for creatinine and urea assay, and urine was used for KIM-1 ELISA. Formalin-submerged tissues were used for histopathological analysis. The level of HIF-1α and VEGF increased significantly from AHH to IHH 1. Cygb and renin expressions peaked at AHH and decreased at subsequent IHH groups. The Nrf2 level and GPx activity didn’t show any difference, but SOD activity peaked at IHH 1. The creatinine level only peaked at IHH 2; other groups remained the same as the control. Urea levels decreased with more IHH sessions, and KIM-1 didn’t show any difference. Our findings exhibit that hypoxia preconditioning by IHH treatment leads to the kidney’s adaptability to hypoxia and does not cause kidney damage.

Abstract

Tourism has an influence on economic growth through several channels (Brida et al, 2010). First, the tourism sector as a foreign exchange earner to obtain capital goods used in the production process (McKinnon, 1964). Second, tourism development stimulates investment in infrastructure (Sakai, 2006). Third, the development of the tourism sector encourages the development of other economic sectors through direct, indirect, and induced effects (Spurr, 2006). Fourth, tourism contributes to increasing job opportunities and increasing income (Lee & Chang, 2008). Fifth, tourism causes positive economies of scale (Weng & Wang, 2004). Tourism is also an important factor in the dissemination of technical knowledge, encouraging research and development, and the accumulation of human capital (Blake et al, 2006). The purpose of this study is to describe the process of Poverty Reduction through the Profit Sharing method in the management of "Snake Island" tourism in Pai Village, Wera District, Bima Regency towards improving the welfare of the community. Qualitative data analysis used an interaction analysis model consisting of data collection, data reduction, data presentation, conclusion drawing, and verification.
