Structures that change their shape in response to external stimuli unfold possibilities for more efficient and versatile production of 3D objects. Direct laser writing (DLW) is a technique based on two-photon polymerization that allows the fabrication of microstructures with complex 3D geometries. Here, it is shown that polymerization shrinkage in DLW can be utilized to create structures with locally controllable residual stresses that enable programmable, self-bending behavior. To demonstrate this concept, planar and 3D-structured sheets are preprogrammed to evolve into bio-inspired shapes (lotus flowers and shark skins)...

OBJECTIVE: To compare the incidence and prevalence of depressive symptoms in atypical parkinsonian (APD) syndromes versus Parkinson disease (PD). METHODS: In a large retrospective patient cohort we analyzed the incidence and prevalence of depressive symptoms using the Beck Depression Inventory (BDI) and evaluated subjects longitudinally on subsequent visits. For individuals who followed in subsequent visits we calculated incidence rates in person-years as a measure of incidence...

BACKGROUND: Trauma accounts for 4.7 million deaths each year, with an estimated 90% of these occurring in LMICs. Approximately half of trauma-related deaths are due to central nervous system injury. OBJECTIVE: Because a thorough understanding of TBI in LMICs is essential to mitigate TBI-related mortality, we established a clinical and radiographic database to characterize TBI in our low-income setting. METHODS: This is a review of prospectively collected data from Kamuzu Central Hospital, a tertiary care center in the capital of Malawi...

BACKGROUND: Osteoporosis is a growing health problem around the world. The increasing incidence of osteoporotic fractures coupled with the lack of knowledge about the disease in the general community means that the disease is continuously increasing the burden on health sector and the general population. The purpose of the study is to assess knowledge, attitudes and practices about osteoporosis among female medical school entrants in Karachi. METHODS: This is a descriptive cross-sectional study conducted amongst 400 female medical school entrants of DOW University of Health Sciences (DUHS) and Jinnah Sindh Medical University (JSMU)...

Endoscopic ultrasound (EUS) was first introduced into medical practice in 1980s as a diagnostic imaging modality for pancreatic pathology. EUS has the unique advantage of combining ultrasound and endoscopy to obtain detailed information of the gastrointestinal tract. Over the past decade, the use of EUS in liver diseases has been increasing. EUS, which was initially used as a diagnostic tool, is now having increasing therapeutic role as well. We provide a review of the application of EUS in the diagnostic and therapeutic aspects of liver disease...

OBJECTIVE: The purpose of this study was to investigate the importance of environments (dry and wet) to dislodge the clasp. MATERIALS AND METHODS: Mandibular test models with natural premolar and molar teeth were used to test four types of clasp (each 12) (Akers, rest plate Akers [RPA], half and half [H-H], and ring clasp) in dry and natural fresh saliva environments. Each clasp was pulled out 10 times with a crosshead speed of 10 mm/min and the force required to withdraw each was measured...

Phenazines are important nitrogen-containing secondary metabolites that display a range of biological functionalities. However, these compounds have shown lethal effects on humans and, the fate of phenazine in the ecosystem remains uncertain. In this study, we investigated that Sphingobium yanoikuyae B1 could utilize phenazine as a sole carbon source for growth. Intermediate produced during phenazine degradation was purified and identified as 1, 2-dihydrogen 1, 2-dihydroxy phenazine. Biphenyl 2, 3-dioxygenase was determined to be the initial dioxygenase for phenazine degradation through gene cloning and whole cell transformation techniques...

Microalgae are one of the oldest microorganisms, that grow in various hostile environments, ranging from deserts to Antarctica. The microalgae sustain life in such harsh environments through generation of secondary metabolites. Microalgae biosynthesize a large number of diverse bioactive metabolites with activities on cancer, neurodegenerative diseases, and infectious diseases. Here, we highlight the bioactive compounds that are isolated from microalgae for the purpose of using them as food, and as chemicals in pharmaceutical industry as new agents with therapeutic benefits...

Turner Syndrome was diagnosed in a 45 years old female, known case of Acute Myeloid Leukaemia (AML) with maturation, on Bone Marrow biopsy. She presented with blurred vision, vertigo, exertional dyspnoea and insomnia. She did not show the typical features of Turner syndrome, but her cytogenetis confirmed the diagnosis. Bone marrow biopsy showed diffuse infiltration of blast cells with cellularity around 80-85% and haematopoietic suppression. Karyotype analysis showed: 45 X, -X, t (8; 21) (q22; q22) [According to The International System for Human Cytogenetic Nomenclature (ISCN)]...

REVIEW
David Maurice Chambers, Bilal Abaid, Umair Gauhar
Pleural effusions occur in 1.5 million patients yearly and are a common cause of dyspnea. For nonmalignant effusions, initial treatment is directed at the underlying cause, but when effusions become refractory to medical therapy, palliative options are limited. Tunneled pleural catheters (TPCs) are commonly used for palliation of malignant effusions, but many clinicians are reluctant to recommend these devices for palliation of nonmalignant effusions, citing concerns of infection, renal failure, electrolyte disturbances and protein-loss malnutrition...

Nanotechnology based therapeutics has emerged as a promising approach for augmenting the activity of existing antimicrobials due to the unique physical and chemical properties of nanoparticles (NPs). Nickel oxide nanoparticles (NiO-NPs) have been suggested as prospective antibacterial and antitumor agent. In this study, NiO-NPs have been synthesized by a green approach using Eucalyptus globulus leaf extract and assessed for their bactericidal activity. The morphology and purity of synthesized NiO-NPs determined through various spectroscopic techniques like UV-Visible, FT-IR, XRD, EDX and electron microscopy differed considerably...

Patients with lung cancer are increasingly seeking complementary and alternative medicine (CAM) to improve their physiological and psychological well-being. This study aimed to assess CAM use among lung cancer patients in Lebanon. Using a cross-sectional design, 150 lung cancer patients attending the Basile Cancer Institute at the American University of Beirut Medical Center were interviewed. Participants completed a questionnaire addressing sociodemographic characteristics, lung cancer condition, and use of CAM...

Conversion of lignocellulosic biomass to biofuels and biomaterials suffers from high production costs associated with biomass pretreatment and enzymatic hydrolysis. In-planta expression of lignocellulose-digesting enzymes is a promising approach to reduce these cost elements. However, this approach faces a number of challenges, including auto-hydrolysis of developing cell walls, plant growth and yield penalties, low expression levels and the limited stability of expressed enzymes at the high temperatures generally used for biomass processing to release fermentable sugars...

PURPOSE: Hypofractionated partial breast irradiation (HPBI) involves treatment to the breast tumor using high doses per fraction. Recent advances in MRI-Linac solutions have potential in being applied to HPBI due to gains in the soft tissue contrast of MRI; however, there are potentially deleterious effects of the magnetic field on the dose distribution. The purpose of this work is to determine the effects of the magnetic field on the dose distribution for HPBI tumors using a tangential beam arrangement (TAN), 5-beam intensity-modulated radiation therapy (IMRT), and volumetric modulated arc therapy (VMAT)...

The α1β2γ2 subtype of GABAA receptors is the most commonly found GABAA receptor subtype in the mammalian cortex and hippocampus. It is expressed heterologously in the Xenopus laevis oocyte as a α1β2γ2S/L subtype for application as an in vitro model for the screening of compounds that modulate receptor activities. In fact, 4-hydroxybenzaldehyde (4-HB) has been identified as one of the major components in Dendrocalamus asper bamboo shoots in our previous study, and the current study showed that at 101.7 μM, 4-HB significantly reduced the GABA-induced chloride current of GABAA receptors expressed on Xenopus oocytes, indicating a possible GABAergic antagonistic effect at high concentrations...
