OBJECTIVE To determine the extent of mitochondrial DNA (mtDNA) damage in systemic lupus erythematosus (SLE) patients compared to healthy subjects and to determine the factors associated with mtDNA damage among SLE patients. METHODS A cross-sectional study was performed in 86 SLE patients (per American College of Rheumatology classification criteria) and 86 healthy individuals matched for age ...

A-weighted equivalent continuous noise levels of nine companies/industries in Jos-Bukuru metropolis were determined by using Impulse Precision Sound Level Meter Type 2209 in conjunction with -Octave Filter set Type 1616 and an audiometric test of five hundred and twenty four workers out of a total of seven hundred and ninety one volunteers interviewed were carried out. The physical measurements...

A method is presented for selecting the subset of identified structural vibration modes to be used in finite element model correlation for structural damage detection. The method is based on a ranking of the modes using measured modal strain energy, and is a function of only the measured modal parameters. It is shown that a mode selection strategy based on maximum modal strain energy produces m...

Robust oscillatory behaviors are common features of circadian and cell cycle rhythms. These cyclic processes, however, behave distinctively in terms of their periods and phases in response to external influences such as light, temperature, nutrients, etc. Nevertheless, several links have been found between these two oscillators. Cell division cycles gated by the circadian clock have been observ...

Benign monoclonal protein was first described by Waldenstrm in 1960 after abnormal narrow hypergammaglobulinemia bands were noted in the serum of healthy individuals on serum protein electrophoresis.[1] In 1978, Kyle coined the term “monoclonal gammopathy of undetermined significance (MGUS)” after observing that asymptomatic patients with monoclonal protein have a higher risk of developing mult...

Leaf venation is a pervasive example of a complex biological network, endowing leaves with a transport system and mechanical resilience. Transport networks optimized for efficiency have been shown to be trees, i.e., loopless. However, dicotyledon leaf venation has a large number of closed loops, which are functional and able to transport fluid in the event of damage to any vein, including the p...

Isolated tomato (Lycopersicon esculentum var. Kc 146) fruit mitochondria could be stored successfully in the frozen state without a cryoprotective agent if the mitochondria were frozen quickly by immersion in liquid nitrogen and later thawed quickly at 30 C. Criteria of freezing damage were rate of respiration, adenosine diphosphate to oxygen ratio, and respiratory control ratio. Marked reducti...

Expansive soils are one of the problematic that can cause damage to structures, such as buildings and roads. In Indonesia, geographical distribution expansive is quite widespread, in many regions including Java, Sumatera, Papua. This study was conducted by reviewing previous research on expansion degree soils. The suitability indicated activity method, Van der Merwe’s criteria, Chen’s criteria ...
