Abstract
The quantitative subcellular distribution of the fatty acid binding protein (FABP) in heart muscle is reported for the first time. A gradient-like distribution according to the following pattern was observed: 6.96 mg X mL-1 on the myofibrils, 2.77 mg X mL-1 in the spaces surrounding the mitochondria, and 2.21 mg X mL-1 in the mitochondria. This heterogeneous distribution suggests that the local in vivo concentration of FABP might fluctuate as a function of time. The consequences of these possible fluctuations, particularly in the mitochondrial vicinity, were analyzed in an in vitro system containing a fixed concentration of cardiac mitochondria and stearic acid but variable concentrations of FABP. Competition for the fatty acid was observed between the mitochondrial membranes and the binding sites on the protein. Maximal binding of fatty acid to FABP was detected in the range of FABP concentration between 1 and 3 mg X mL-1. Remarkably, in this concentration range, two emerging peaks of beta-oxidative activity were also detected. As a major conclusion, it appears that the fatty acid pool, bound to FABP, is the source of fatty acid providing the beta-oxidative system with substrate. The mechanism of fatty acid transfer from this pool toward the beta-oxidative system remains an open question. However, it is suggested that a gradient-like distribution of FABP in the mitochondrial vicinity leads to the coexistence of multispecies of the protein by self-aggregation. Only two of these species seem to be involved in this fatty acid transfer. As a consequence, a strong modulation of fatty acid beta-oxidation rate is observed in isolated mitochondria when the concentrations of these two species are allowed to fluctuate. In conclusion, this unique cardiac fatty acid carrier, via its self-aggregation capacity and its in vivo gradient-like distribution, may act as a powerful effector in the regulation of heart energy.

Abstract
This study presents a novel approach to synthesize glycogenic gold nanoparticles (glycogenic GNps) capped with glycated products (Schiff's base, Heyns products, fructosylamine etc.). These glycogenic GNps have been found to be active against human osteosarcoma cell line (Saos-2) with an IC50 of 0.187 mM, while the normal human embryonic lung cell line (L-132) remained unaffected up to 1mM concentration. The size of glycogenic GNps can also be controlled by varying the time of incubation of gold solution. Glycation reactions involving a combination of fructose and HSA (Human Serum Albumin) were found to be effective in the reduction of gold to glycogenic GNps whereas glucose in combination with HSA did not result in the reduction of gold. The progress of the reaction was followed using UV-visible spectroscopy and NBT (Nitroblue tetrazolium) assay. The glycogenic GNps were found to be spherical in shape with an average size of 24.3 nm, in a stable emulsion. These GNps were characterized using UV-visible spectroscopy, zeta potential analysis, transmission electron microscopy (TEM) and scanning electron microscopy (SEM).

Abstract
BACKGROUND Leber's congenital amaurosis (LCA) represents the earliest and severest form of retinal dystrophy leading to congenital blindness. A total of 20% of children attending blind schools have this disease. LCA has a multigenic basis and is proving central to our understanding of the development of the retina. We describe the clinical and molecular genetic features of four inbred pedigrees from neighbouring remote villages in northern Pakistan, in which some of the affected members have concurrent keratoconus. METHODS History-taking and physical and eye examinations were performed in the field. Venipuncture, DNA extraction, studies of linkage to known LCA genes, automated sequencing and polymorphism analyses for haplotype assessments were done. RESULTS We examined 12 affected and 15 unaffected family members. By history, there were an additional nine blind people in the four pedigrees. In each pedigree a consanguineous marriage was evident. We found a homozygous nonsense mutation in the AIPL1 gene, which replaces a tryptophan with a stop codon (Trp278X). The phenotype is severe and variable, despite the common molecular genetic etiology in each family. Affected patients had hand motion to no light perception vision and fundus findings ranging from maculopathy to diffuse pigmentary retinopathy. Three affected members had definite keratoconus, and two were suspects based on mild cone formation in the cornea of at least one eye. INTERPRETATION We have identified four Pakistani families with a severe form of LCA that is associated with severe keratoconus in some affected members. The molecular etiology in all four families is a homozygous nonsense mutation, Trp278X, in the photoreceptor-pineal gene AIPL1. To our knowledge, this is one of the first phenotype-genotype correlations of AIPL1-associated LCA.

Abstract
In this study, an eco‐friendly biosynthesis of stable gold nanoparticles (T‐GNPs) was carried out using different concentrations of tomato juice (nutraceuticals) as a reducing agent and tetrachloroauric acid as a metal precursor to explore their potential application in cancer therapeutics. The synthesis of T‐GNPs was monitored by UV‐visible absorption spectroscopy, which unveiled their formation by exhibiting the typical surface plasmon absorption maxima at 522 nm. The size of T‐GNPs was found to be 10.86 ± 0.6 nm. T‐GNPs were characterised by dynamic light scattering, zeta potential, transmission electron microscopy analysis and Fourier transform infrared spectroscopy. T‐GNPs were further investigated for their anti‐cancer activity against human lung carcinoma cell line (A549) and human cervical cancer cell line wherein the IC50 values were found to be 0.286 and 0.200 mM, respectively. T‐GNPs inhibited the growth of cancer cells by generating ROS and inducing apoptosis. T‐GNPs were found highly effective by virtue of their size, metallic property and capping molecules. Thus, this study opens up the prospects of using nutraceutical (tomato juice) as nutratherapeutic agent (T‐GNPs) against critical diseases like lung cancer and cervical cancer.

Abstract
Autophagy is a process essential for cellular energy consumption, survival, and defense mechanisms. The role of autophagy in several types of human cancers has been explicitly explained; however, the underlying molecular mechanism of autophagy in glioblastoma remains ambiguous. Autophagy is thought to be a “double-edged sword”, and its effect on tumorigenesis varies with cell type. On the other hand, autophagy may play a significant role in the resistance mechanisms against various therapies. Therefore, it is of the utmost importance to gain insight into the molecular mechanisms deriving the autophagy-mediated therapeutic resistance and designing improved treatment strategies for glioblastoma. In this review, we discuss autophagy mechanisms, specifically its pro-survival and growth-suppressing mechanisms in glioblastomas. In addition, we try to shed some light on the autophagy-mediated activation of the cellular mechanisms supporting radioresistance and chemoresistance in glioblastoma. This review also highlights autophagy’s involvement in glioma stem cell behavior, underlining its role as a potential molecular target for therapeutic interventions.

Abstract
Mid-infrared vertical external cavity surface emitting lasers (VECSELs) for 5 microm in wavelength have been realized. The active parts are of a simple structure, either a 2 microm thick PbTe gain layer or two 150 nm PbTe layers embedded in Pb(1-x)Eu(x)Te barriers. Epitaxial 2.5 pair Pb(1-y)Eu(y)Te/BaF(2) Bragg mirrors are employed to form the cavity, and an Al layer is deposited for improved heat dissipation. Emission up to 300 mW(p) is observed with microsecond pulses or 3 mW cw at 100 K is obtained. Quantum efficiency is up to 14%, and lasing occurs up to 175 K when pumped with a 1.55 microm wavelength pump laser.

Abstract
Introduction One session of high energy extracorporeal shockwave therapy (ESWT) was found to improve the healing of anterior cruciate ligament (ACL) after reconstruction in animal and human studies. This study investigated the effects of three and six sessions of low energy ESWT on graft incorporation and knee functions post ACL reconstruction in humans. Materials and methods Thirty participants with ACL injuries were recruited and assigned equally into three groups with 10 participants per group (n=10). Participants in the control group received physiotherapy alone without low energy ESWT. Participants in the 3ESWT group underwent three sessions of low energy ESWT (one session per week) combined with physiotherapy, and participants in the 6ESWT group received six sessions of low energy ESWT (one session per week) combined with physiotherapy. However, five participants were lost to follow-up. Evaluations of graft incorporation of the tibial tunnel using magnetic resonance (MRI) and Lysholm score were carried out before ACL reconstruction and after six months post ACL reconstruction. Results The number of grafts with partial incorporation in the tibia tunnel in 6ESWT was significantly higher compared with the number of grafts with non-incorporation at six months post-operatively, X2 (1, N=9) =5.44, p =0.02. However, there was no significant difference between frequencies of graft incorporation in tibia tunnel in the control and 3ESWT groups, X2 (1, N=7) =3.57, p =0.06 and X2 (1, N=9) =2.78, p =0.10, respectively at 6 months postoperatively. Lysholm scores were significantly higher at 6 months post ACL reconstruction compared to the baseline value for each group (p<0.002, respectively). However, there was no significant difference in the Lysholm score between each group (F = 2.798, p = 0.083). Conclusions Six sessions of low energy ESWT improved graft incorporation in the tibial tunnel. Both three and six sessions of low energy of ESWT does not affect the knee function score at six months post ACL reconstruction.

Abstract
Forty-two patients aged between 6 and 61 years (mean: 33.5 years) with psoriasis of the scalp were enrolled in this study. Twenty-seven patients (69%) were males and 15 (31%) were females. The aim of our study was to evaluate the efficacy, safety and tolerability of topical calcipotriol 50 micrograms/g/ml solution vs. betamethasone valerate 1% lotion in the treatment of psoriasis of the scalp. The study was randomized with the twice-daily application of either calcipotriol solution or betamethasone valerate lotion for 6 weeks. Treatment evaluation was clinically based on signs of psoriasis (thickness, redness, scaliness) which were scored from 0 = absent to 4 = severest possible involvement and was performed at the start of treatment and at weeks 2 and 6 of treatment. The results showed a marked improvement and clearance at the end of treatment in 15 (72.8%) of the 24 patients in the calcipotriol group and in 13 of the 18 patients (72%) in the betamethasone group. The mean total sign score at baseline was 5.1 in the calcipotriol group and 5.4 in the betamethasone valerate group. At the end of treatment, this score was decreased to 2.1 and 1.49, respectively. No significant adverse effects were reported in either group except in two patients (8.3%) in the calcipotriol group who developed signs of irritation including itching and erythema. In conclusion, both drugs were effective and well tolerated in the treatment of scalp psoriasis but in some patients calcipotriol had to be given for more prolonged courses.

Abstract
Thirty-nine patients with a clinical diagnosis of palmoplantar psoriasis [23 (58%) males and 16 (42%) females] were included in this study with the aim of evaluating the efficacy of occlusive calcipotriol 50 micrograms/mg ointment vs. nonocclusive therapy. Patients were randomized to either twice-weekly overnight calcipotriol ointment under occlusion or twice-daily topical nonocclusive application of the same ointment for 6 weeks. The effect of treatment was assessed on the basis of a psoriasis signs score for erythema, thickness and scaliness, which was graded from 0 (absent) to 4 (most severe) at the first visit, after 2 weeks and at the end of treatment. Analysis of our results showed that twice-weekly occlusive calcipotriol ointment was as effective as the twice-daily application. The mean total score at baseline was 6 for the occlusive group and 6.1 for the nonocclusive group. The score decreased to 1.5 in both groups at the end of treatment. No significant adverse effects were reported by patients or investigators. We conclude that occlusive calcipotriol ointment is effective in the treatment of palmoplantar psoriasis and may produce even better results with more frequent use, such as application on alternate days.

Abstract
Sensitizing health providers to customers' needs and women's health remains a challenge to the Pakistani health system. The Health Workers for Change methodology has been demonstrated to improve provider-client relationships in certain African and Latin American countries. This paper describes the experience of using Health Workers for Change participatory workshops in Pakistan to sensitize male and female health providers to gender issues. Health care providers identified the unmet needs of women clients as a function of individual, household and societal factors, and, unlike the African experience with this tool, not predominantly confined to factors associated with the health facility.

Abstract
The disease early warning system (DEWS) was introduced in the immediate aftermath of the 2005 earthquake in Pakistan, with the objective to undertake prompt investigation and mitigation of disease outbreaks. The DEWS network was replicated successfully during subsequent flood and earthquake disasters as well as during the 2008-09 internally displaced persons' crisis. DEWS-generated alerts, prompt investigations and timely responses had an effective contribution to the control of epidemics. Through DEWS, 1360 reported alerts during 2005-09 averted the risk of disease outbreaks through pre-emptive necessary measures, while the 187 confirmed outbreaks were effectively controlled. In the aftermath of the disasters, DEWS technology also facilitated the development of a disease-surveillance system that became an integral part of the district health system. This study aims to report the DEWS success and substantiate its lead role as a priority emergency health response intervention.

Abstract
In diabetes and its associated pathologies, glycation, α-amylase, and α-glucosidase play crucial roles. This study introduces a novel tripeptide, RWW, designed to target glycation and key enzymes in diabetes management. Using in silico methods, RWW was optimized to interact with the glycation-prone Human serum albumin (HSA) sites, as well as inhibit α-amylase and α-glucosidase. Molecular docking and dynamics confirmed its stability. In-vitro assays confirmed RWW's potent inhibition of glycation (84.00 %) and enzyme activities, while in-vivo experiments demonstrated its hypoglycemic and lipid-lowering effects in diabetic mice. Histopathological analysis of kidney tissues further highlighted its protective impact. RWW represents a promising anti-diabetic candidate with dual therapeutic functions.

Their key technical specifications include L-I-V curves, optical and RF beating spectra, relative intensity noise (RIN), and optical phase noise of each individual wavelength channel, as well as timing jitter are investigated. Data bandwidth transmission capacity of 5.376 Tbit/s and 10.3 Tbit/s respectively in the PAM-4 and 16-QAM modulation formats are demonstrated by only using a single QD MWL chip. We have also developed a novel monolithic InAs/InP QD dual-wavelength (DW) DFB laser as a compact optical beat source to generate millimeter-wave (MMW) signals. Because of using a common cavity, highly coherent and correlated optical modes with optical linewidth as low as 15.83 kHz, spectrally pure MMW signals around 46.8 GHz with a linewidth down to 26.1 kHz were experimentally demonstrated. By using this QD DW-DFB laser, a 1Gbaud (2Gbps) MMW over-fiber transmission link is demonstrated with PAM-4 signals. The results show that the demonstrated device is suitable for high speed high capacity MMW fiber-wireless integrated fronthaul of 5G networks.
