Iron deficiency anemia is the most frequent nutritional deficiency disorder. Conventionally administered oral iron is associated with gastrointestinal intolerance that affects the outcomes and compliance. Liposomal iron is associated with increased absorption without causing significant adverse effects. In this review, we have discussed the technology of liposomal iron preparation, mechanisms of its absorption and clinical evidence on its utility in iron deficiency states in pregnant and non-pregnant women. Based on the available evidence, we compared liposomal iron to conventional oral iron. Encapsulation of micronized iron in liposomes is associated with lesser exposure to gastric contents, lesser interaction with food contents, no exposure to different digestive juices, targeted delivery of iron and allows lower doses to be administered in lieu of direct absorption without need for protein carriers. The available evidence suggests that liposomal iron significantly increases hemoglobin, ferritin levels in pregnant women as well as in women with iron deficiency.

Ozone (O3) is a stratospheric layer that plays important role in providing support to humans for their survival. It is an essential factor for many global, biological and environmental phenomena. The ultra-violet (UV) rays emitted from sun are captured by ozone and thereby provide a stable ontological structure in the biosphere. Various anthropogenic activities such as emissions of CFCs, HCFCs and other organo-halogens lead to the depletion of ozone. The ozone depletion resulted in secondary production of an ozone layer near the ground (terrestrial ozone layer), which is responsible for adverse effects on plants, humans and environment with increased number of bronchial diseases in humans. The mutations caused by UV rays result in variation in morphogenic traits of plants which ultimately decreases crop productivity. However, UV radiation is required in optimum intensity for both plants and animals. This review takes into an account the wide ranging effects of ozone depletion with a majority of them being detrimental to the plant system.

GaN/InGaN based violet light emitting diodes (LEDs), emitting at 430 nm, have been grown on conventional single side polished (SSP) and patterned sapphire substrates (PSS). Characteristics of the epitaxial wafers and subsequently fabricated LEDs have been analyzed. The photoluminescence (PL) peaks have been observed at 428.1 nm 426.1 nm for the epitaxial layers on SSP and PSS respectively. The PL intensity is 2.9 times higher in the case of PSS. The electroluminescence (EL) peaks have been observed at 430.78 nm and 430.35 nm for the LEDs on SSP and PSS respectively. The light output from LED fabricated on the PSS is 2.15 times higher than that of the LED on SSP at a forward current of 100 mA.

Iron deficiency is the most common nutritional deficiency leading to anemia in pregnancy. Conventionally, non-heme form of iron salts has been the mainstay of treatment. However, patient compliance is an important concern with existing oral iron therapy due to gastrointestinal side effects. Heme iron, a better bioavailable and tolerable form of iron can be suitable form of iron for supplementation in pregnancy. Evidence suggests its utility in pregnancy for treatment of iron deficiency anemia with benefits extending to postpartum period. Effective transfer across placenta to fetus further supports its utility in pregnancy. This review discusses in details the absorption kinetics along with clinical evidence on efficacy, safety, and tolerability of heme-iron supplementation in iron deficiency anemia of pregnancy.

Coronal shear fractures of distal humerus involving the capitellum and the trochlea are rare injuries with articular complexity, and are technically challenging for management. With better understanding of the anatomy and imaging advancements, the complex nature of these fractures is well appreciated now. These fractures involve metaphysealcomminution of lateral column and associated intraarticular injuries are common. Previously, closed reduction and excision were the accepted treatment but now preference is for open reduction and internal fixation with an aim to provide stable and congruent joint with early range of motion of joint. Various approaches including extensile lateral, anterolateral and posterior approaches have been described depending on the fracture pattern and complexity. Good to excellent outcome have been reported with internal fixations and poor results are noted in articular comminution with associated articular injuries. Various implants including headleass compression screws, minifragment screws, bioabsorbable implants and column plating are advocated for reconstruction of these complex fractures. Inspite of articular fragments being free of soft tissue attachments the rate of osteonecrosis and osteoarthritis is reported very less after internal fixation. This article summarizes the diagnostic and treatment strategies for these rare fractures and recommendations for management.

概述苏云金杆菌与球形芽孢杆菌是多种媒介昆虫的高效生物控制剂,它们所含有毒素的类芽孢体对蚊幼虫具有极强的毒性作用。球形芽孢杆菌的类芽孢体对库蚊和按蚊幼虫毒效很高。在蚊幼中肠的碱性环境与蛋白酶作用下,类芽孢体很快被溶解,释放出毒素使中肠上皮细胞破坏、分离和分裂(这一点与苏云金杆菌类同)。有人认为中肠上皮细胞的肿胀和破坏是昆虫致死的关键原因。
