Abstract
Cardiovascular disease (CVD), exemplified by coronary artery disease (CAD), is a global health concern, escalating in prevalence and burden. The etiology of CAD is intricate, involving different risk factors. CVD remains a significant cause of mortality, driving the need for innovative interventions like percutaneous coronary intervention and vascular stents. These stents aim to minimize restenosis, thrombosis, and neointimal hyperplasia while providing mechanical support. Notably, the challenges of achieving ideal stent characteristics persist. An emerging avenue to address this involves enhancing the mechanical performance of polymeric bioresorbable stents using additive manufacturing techniques And Three-dimensional (3D) printing, encompassing various manufacturing technologies, has transcended its initial concept to become a tangible reality in the medical field. The technology's evolution presents a significant opportunity for pharmaceutical and medical industries, enabling the creation of targeted drugs and swift production of medical implants. It revolutionizes medical procedures, transforming the strategies of doctors and surgeons. Patient-specific 3D-printed anatomical models are now pivotal in precision medicine and personalized treatment approaches. Despite its ongoing development, additive manufacturing in healthcare is already integrated into various medical applications, offering substantial benefits to a sector under pressure for performance and cost reduction. In this review primarily emphasizes stent technology, different types of stents, highlighting its application with some potential complications. Here we also address their benefits, potential issues, effectiveness, indications, and contraindications. In future it can potentially reduce complications and help in improving patients' outcomes. 3DP technology offers the promise to customize solutions for complex CVD conditions and help or fostering a new era of precision medicine in cardiology.

Abstract
BACKGROUND Human papillomavirus (HPV) vaccination is one of the crucial national vaccination programs aimed at reducing the prevalence of the diseases associated with HPV infections, which continue to pose a global health concern. However, a significant disparity exists in the distribution of HPV vaccine, particularly in low-middle income countries where the cost of HPV vaccine becomes a major obstacle. Thus, it is essential to ensure the availability of an economically feasible HPV vaccine, necessitating immediate efforts to enhance the cost-effectiveness of vaccine production. This study aimed to develop an efficient production system for the recombinant HPV type 52 L1 protein as HPV vaccine material using methylotrophic yeast Hansenula polymorpha expression system. RESULTS This study presents an in-depth examination of the expression and scale-up production of HPV type 52 L1 protein using DASGIP® parallel bioreactor system. The pHIPX4 plasmid, which is regulated by the MOX promoter, generates stable clones that express the target protein. Cultivation employing the synthetic medium SYN6(10) with controlled parameters (e.g. temperature, pH, feeding strategy, and aeration) produces 0.15 µg/mL of HPV type 52 L1 protein, suggesting a possibility for scaling up to a higher production level. CONCLUSION The scale-up production of HPV type 52 L1 protein using Hansenula polymorpha expression system described in this study provides an opportunity for an economical manufacturing platform for the development of the HPV vaccine.

Abstract
BACKGROUND Cervical cancer caused by the human papillomavirus (HPV) is one of the most frequent malignances globally. HPV 52 is a high-risk cancer-causing genotype that has been identified as the most prevalent type in Indonesia. Virus-like particles (VLP)-based vaccinations against HPV infection could benefit from self-assembled VLP of L1 capsid protein. RESULT The recombinant HPV 52 L1 was expressed in Pichia pastoris on a shake-flask scale with 0.5% methanol induction in this study. The copy number was used to compare the expression level and stability. The colony that survived on a solid medium containing 2000 μg/ml of Zeocin was selected and cultured to express HPV 52 L1. DNA was extracted from the chosen colony, and the copy was determined using qPCR. HPV 52 L1 protein was then purified through fast performance liquid chromatography. Transmission electron microscopy (TEM) evaluation confirmed the VLP self-assembly. The genomic DNA remained intact after 100 generations of serial cultivation under no selective pressure medium conditions, and the protein produced was relatively stable. However, the band intensity was slightly lower than in the parental colony. In terms of copy number, a low copy transformant resulted in low expression but produced a highly stable recombinant clone. Eventually, the L1 protein expressed in Pichia pastoris can self-assemble into VLP. Therefore, recombinant HPV possesses a stable clone and the ability to self-assemble into VLP. CONCLUSION The recombinant L1 HPV 52 protein is successfully expressed in P. pastoris within a size range of approximately 55 kDa and demonstrated favorable stability. The L1 protein expressed in Pichia pastoris successful self-assembled of HPV VLPs, thereby establishing their potential efficacy as a prophylactic vaccine.

Abstract
α-Mangostin (a xanthone derivative found in the pericarp of Garcinia mangostana L.) and propolis extract (which is rich in flavonoids and phenols) are known for their antioxidant properties, making them potential supplements for the treatment of oxidative stress-related conditions. However, these two potential substances have the same primary drawback, which is low solubility in water. The low water solubility of α-mangostin and propolis can be overcome by utilizing nanotechnology approaches. In this study, a propolis-based nanostructured lipid carrier (NLC) system was formulated to enhance the delivery of α-mangostin. The aim of this study was to characterize the formulation and investigate its influence on the antioxidant activity of α-mangostin. The results showed that both unloaded propolis-based NLC (NLC-P) and α-mangostin-loaded propolis-based NLC (NLC-P-α-M) had nanoscale particle sizes (72.7 ± 1.082 nm and 80.3 ± 1.015 nm, respectively), neutral surface zeta potential (ranging between +10 mV and -10 mV), and good particle size distribution (indicated by a polydispersity index of <0.3). The NLC-P-α-M exhibited good entrapment efficiency of 87.972 ± 0.246%. Dissolution testing indicated a ~13-fold increase in the solubility of α-mangostin compared to α-mangostin powder alone. The incorporation into the propolis-based NLC system correlated well with the enhanced antioxidant activity of α-mangostin (p < 0.01) compared to NLC-P and α-mangostin alone. Therefore, the modification of the delivery system by incorporating α-mangostin into the propolis-based NLC overcomes the physicochemical challenges of α-mangostin while enhancing its antioxidant effectiveness.

Abstract
Polymicrobial wound infections are a major cause of infectious disease-related morbidity and mortality worldwide. In this study, we prepared a nitric oxide (NO)-releasing oxidized bacterial cellulose/chitosan (BCTO/CHI) crosslinked hydrogel to effectively treat polymicrobial wound infections. Linear polyethyleneimine diazeniumdiolate (PEI/NO) was used as the NO donor. The aldehyde group of BCTO and the amine of CHI were used as crosslinked hydrogel-based materials; their high NO loading capacity and antibacterial activity on the treatment of polymicrobial-infected wounds were investigated. The blank and NO-loaded crosslinked hydrogels, namely BCTO-CHI and BCTO-CHI-PEI/NO, were characterized according to their morphologies, chemical properties, and drug loading. BCTO-CHI-PEI/NO exhibited sustained drug release over four days. The high NO loading of BCTO-CHI-PEI/NO enhanced the bactericidal efficacy against multiple bacteria compared with BCTO-CHI. Furthermore, compared with blank hydrogels, BCTO-CHI-PEI/NO has a favorable rheological property due to the addition of a polymer-based NO donor. Moreover, BCTO-CHI-PEI/NO significantly accelerated wound healing and re-epithelialization in a mouse model of polymicrobial-infected wounds. We also found that both crosslinked hydrogels were nontoxic to healthy mammalian fibroblast cells. Therefore, our data suggest that the BCTO-CHI-PEI/NO developed in this study improves the efficacy of NO in the treatment of polymicrobial wound infections.

Abstract
This study demonstrates the development of a nitric oxide (NO)-releasing hydrogel wound dressing and its efficacy at accelerating methicillin-resistant Staphylococcus aureus (MRSA)-infected wound healing. A DETA/NONOate-doped alginate (Alg-DETA/NO) hydrogel was synthesized using alginate as a hydrogel-forming wound dressing material and diethylenetriamine/diazeniumdiolate (DETA/NONOate) as an NO donor. Alg-DETA/NO exhibited a prolonged NO release profile over a period of 4 days. The rheological properties of Alg-DETA/NO did not differ significantly from those of pure alginate. Importantly, Alg-DETA/NO showed potent antibacterial activity against MRSA, with minimal toxicity to mouse fibroblasts. The application of Alg-DETA/NO to MRSA-infected wounds in a mouse model showed a favorable wound healing with accelerated wound-size reduction and reduced skin bacterial infection. Additionally, histological examination revealed that Alg-DETA/NO reduced inflammation at the wound site and promoted re-epithelialization, angiogenesis, and collagen deposition. Thus, Alg-DETA/NO presented herein could serve as a safe and potent hydrogel dressing for the treatment of MRSA-infected wounds.

Abstract
Although nitric oxide (NO) has been emerging as a novel local anticancer agent because of its potent cytotoxic effects and lack of off-target side effects, its clinical applications remain a challenge because of the short effective diffusion distance of NO that limits its anticancer activity. In this study, we synthesized albumin-coated poly(lactic-co-glycolic acid) (PLGA)-conjugated linear polyethylenimine diazeniumdiolate (LP/NO) nanoparticles (Alb-PLP/NO NPs) that possess tumor-penetrating and NO-releasing properties for an effective local treatment of melanoma. Sufficient NO-loading and prolonged NO-releasing characteristics of Alb-PLP/NO NPs were acquired through PLGA-conjugated LP/NO copolymer (PLP/NO) synthesis, followed by nanoparticle fabrication. In addition, tumor penetration ability was rendered by the electrostatic adsorption of the albumin on the surface of the nanoparticles. The Alb-PLP/NO NPs showed enhanced intracellular NO delivery efficiency and cytotoxicity to B16F10 murine melanoma cells. In B16F10-tumor-bearing mice, the Alb-PLP/NO NPs showed improved extracellular matrix penetration and spatial distribution in the tumor tissue after intratumoral injection, resulting in enhanced antitumor activity. Taken together, the results suggest that Alb-PLP/NO NPs represent a promising new modality for the local treatment of melanoma.

Abstract
Bacterial biofilms on wounds impair the healing process and often lead to chronic wounds. Chitosan is a well-known biopolymer with antimicrobial and anti-biofilm effects. S-nitrosoglutathione (GSNO) has been identified as a promising nitric oxide (NO) donor to defend against pathogenic biofilms and enhance wound healing activities. In this study, we prepared NO-releasing chitosan film (CS/NO film) and evaluated its anti-biofilm activity and in vivo wound healing efficacy against methicillin-resistant Staphylococcus aureus (MRSA) biofilm-infected wounds in diabetic mice. The in vitro release study showed sustained release of NO over 3 days in simulated wound fluid. The CS/NO film significantly enhanced antibacterial activity against MRSA by > 3 logs reduction in bacterial viability. Moreover, CS/NO film exhibited a 3-fold higher anti-biofilm activity than the control and CS film. In in vivo MRSA biofilm-infected wounds, the CS/NO film-treated group showed faster biofilm dispersal, wound size reduction, epithelialization rates, and collagen deposition than the untreated and CS film-treated groups. Therefore, the CS/NO film investigated in this study could be a promising approach for the treatment of MRSA biofilm-infected wounds.

Abstract
The eradication of bacteria from wound sites and promotion of healing are essential for treating infected wounds. Nitric oxide (NO) is desirable for these purposes due to its ability to accelerate wound healing and its broad-spectrum antibacterial effects. We developed an in situ hydrogel-forming/NO-releasing powder dressing (NO/GP), which is a powder during storage and forms a hydrogel when applied to wounds, as a novel NO-releasing formulation to treat infected wounds. An NO/GP fine powder (51.5 μm) was fabricated by blending and micronizing S-nitrosoglutathione (GSNO), alginate, pectin, and polyethylene glycol (PEG). NO/GP remained stable for more than four months when stored at 4 or 37 °C. When applied to wounds, NO/GP absorbed wound fluid and immediately converted to a hydrogel. Additionally, wound fluid triggered a NO release from NO/GP for more than 18 h. The rheological properties of hydrogel-transformed NO/GP indicated that NO/GP possesses similar adhesive properties to marketed products (Vaseline). NO/GP resulted in a 6-log reduction in colony forming units (CFUs) of methicillin resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa, which are representative drug-resistant gram-positive and -negative bacteria, respectively. The promotion of wound healing by NO/GP was demonstrated in mice with full-thickness wounds challenged with MRSA and P. aeruginosa. Thus, NO/GP is a promising formulation for the treatment of infected wounds.

Abstract
Adhesion of nanoparticles (NPs) to the bacterial cell wall by modifying their physicochemical properties can improve the antibacterial activity of antibiotic. In this study, we prepared positively charged clindamycin-loaded poly (lactic-co-glycolic acid)-polyethylenimine (PLGA-PEI) nanoparticles (Cly/PPNPs) and negatively charged clindamycin-loaded PLGA NPs (Cly/PNPs) and investigated the effect of NP adhesion to bacteria on the treatment of methicillin-resistant Staphylococcus aureus (MRSA)-infected wounds. The Cly/PPNPs and Cly/PNPs were characterized according to particle size, polydispersity index, surface charge, and drug loading. Both Cly/PPNPs and Cly/PNPs exhibited sustained drug release over 2 days. The Cly/PPNPs bind to the MRSA surface, thereby enhancing bactericidal efficacy against MRSA compared with the Cly/PNPs. Furthermore, compared with other groups, Cly/PPNPs significantly accelerated the healing and re-epithelialization of wounds in a mouse model of a MRSA-infected wounds. We also found that both NPs are harmless to healthy fibroblast cells. Therefore, our results suggest that the Cly/PPNPs developed in this study improve the efficacy of clindamycin for the treatment of MRSA-infected wounds.

Abstract
Wounds infected with methicillin-resistant Staphylococcus aureus (MRSA) biofilm represent a high risk in patients with diabetes. Nitric oxide (NO) has shown promise in dispersing biofilm and wound healing. For an effective treatment of MRSA biofilm-infected wounds, however, NO needs to be supplied to the biofilm matrix in a sustainable manner due to a short half-life and limited diffusion distance of NO. In this study, polyethylenimine/diazeniumdiolate (PEI/NONOate)-doped PLGA nanoparticles (PLGA-PEI/NO NPs) with an ability to bind to the biofilm matrix are developed to facilitate the NO delivery to MRSA biofilm-infected wound. In simulated wound fluid, PLGA-PEI/NO NPs show an extended NO release over 4 days. PLGA-PEI/NO NPs firmly bind to the MRSA biofilm matrix, resulting in a greatly enhanced anti-biofilm activity. Moreover, PLGA-PEI/NO NPs accelerate healing of MRSA biofilm-infected wounds in diabetic mice along with complete biofilm dispersal and reduced bacterial burden. These results suggest that the biofilm-binding NO-releasing NPs represent a promising NO delivery system for the treatments of biofilm-infected chronic wounds.

Abstract
Particle shape has been recognized as one of the key properties of nanoparticles in biomedical applications including targeted drug delivery. Targeting ability of shape-engineered particles depends largely on targeting ligands conjugated on the particle surface. However, poor capacity for surface ligand conjugation remains a problem in anisotropic nanoparticles made with biodegradable polymers such as PLGA. In this study, we prepared anisotropic PLGA nanoparticles with abundant conjugatable surface functional groups by a film stretching-based fabrication method with poly (ethylene-alt-maleic acid) (PEMA). Scanning electron microscopy images showed that microrods and nanorods were successfully fabricated by the PEMA-based film stretching method. The presence of surface carboxylic acid groups was confirmed by confocal microscopy and zeta potential measurements. Using the improved film-stretching method, the amount of protein conjugated to the surface of nanorods was increased three-fold. Transferrin-conjugated, nanorods fabricated by the improved method exhibited higher binding and internalization than unmodified counterparts. Therefore, the PEMA-based film-stretching system presented in this study would be a promising fabrication method for non-spherical biodegradable polymeric micro- and nanoparticles with high capacity of surface modifications for enhanced targeted delivery.

Abstract
Oral colon-targeted drug delivery has gained popularity as an effective strategy for treatment of inflammatory bowel disease (IBD). In this study, we prepared colon-targeted dexamethasone microcrystals (DXMCs) coated with multilayers of chitosan oligosaccharide (CH), alginate (AG), and finally Eudragit S 100 (ES) (ES1AG4CH5-DXMCs) using a layer-by-layer (LBL) coating technique. Particle size, surface charge, in vitro drug release, and in vivo anti-inflammatory activity of ES1AG4CH5-DXMCs were evaluated. ES1AG4CH5-DXMCs had an average particle size of 2.34 ± 0.19 μm and a negative surface charge of - 48 ± 9 mV. ES1AG4CH5-DXMCs demonstrated pH-dependent dexamethasone release, avoiding initial burst drug release in acidic pH conditions of the stomach and small intestine, and providing subsequent sustained drug release in the colonic pH. Importantly, ES1AG4CH5-DXMCs exhibited a significant therapeutic activity in a mouse model of colitis compared to other DXMCs. Overall, the LBL-coated DXMCs presented here could be a promising colon-targeted therapy for IBD.

Abstract
More than 100 million people in the United States of America alone suffer from age-related presbyopia caused by a loss of focal accommodation of the eye crystalline lens as the lens stiffens with age. The resulting accommodative error or lag produces blurred images of objects placed at different distances. Conventional fixed uniform or graded power eyeglasses cannot provide accommodation thus resulting in significant visual impairment. In this paper we will discuss the implementation of lightweight auto-focusing eyeglasses that augment the accommodative range thus partially or fully restoring normal vision function. The paper discusses some aspects of the construction of tunable power eyepieces and the implementation of accommodation correction algorithms.

Abstract
ObjectiveThis paper intends to show the challenges faced by poor Bangladeshi Muslim women from lower socioeconomic status, in case of divorce or separation in marriage. Participants will also learn how they earn for their living and how they raise their children if any. This paper will also present the obligations of marriage in Islam, which may reduce the hazards in their life.MethodSome women were interviewed from lower socioeconomic status from slum area of Dhaka. Researcher took their consent before interview had started. They were asked about their age, educational status, duration of marriage, type of work they do for livelihood, whether they get any maintenance money from the husbands in case of separation, expenses for raising children if any, any criticize from the friends and relatives, etc. The answers were noted carefully.ResultsAfter critical analysis of the interview it was revealed that they were leading their lives on their own, most of them were not aware of their rights relating to marriage in Islam. Two of the women had to pay dowry. Some of them were addicted to tobacco leaf taken with betel nut and PAN, a special form of leaf.ConclusionsIn conclusion, it can be said that these women lead their lives with courage. They need to be educated about their marriage rights in Islam and legal help. At a time, men should be educated about the marriage rights of the wives and the evil effects of dowry in the society.Disclosure of interestThe author has not supplied his/her declaration of competing interest.

Abstract
This review article is aimed to delineate the potential role of hormones in the treatment and diagnosis of cardiovascular diseases with special emphasis on the nitric oxide (NO) involved mechanisms. This review will also offer an overview on current and future hormone usages, pathophysiology, clinical features, absorption mechanisms and adverse effects. The hormone therapies against cardiovascular diseases as well as their treatment strategies, delivery routes and carriers were thoroughly discussed. Ongoing and future basic and clinical research with hormone will provide important insights into efficient treatment strategies against cardiovascular diseases. It was necessary to explore advanced delivery systems, such as drug eluting stent, microneedles, nanotechnology and stem cell preconditioning, for an efficient delivery of hormones against cardiovascular diseases. The future is enlightened with the advent of novel, safer and more effective carriers for hormone delivery as well as learning how to maximize the therapeutic efficacy against cardiovascular diseases.

Abstract
Rice (Oryza sativa L.) blast disease is one of the most destructive rice diseases in the world. The fungal pathogen, Magnaporthe oryzae, is the causal agent of rice blast disease. Development of resistant cultivars is the most preferred method to achieve sustainable rice production. However, the effectiveness of resistant cultivars is hindered by the genetic plasticity of the pathogen genome. Therefore, information on genetic resistance and virulence stability are vital to increase our understanding of the molecular basis of blast disease resistance. The present study set out to elucidate the resistance pattern and identify potential simple sequence repeat markers linked with rice blast disease. A backcross population (BC2F1), derived from crossing MR264 and Pongsu Seribu 2 (PS2), was developed using marker-assisted backcross breeding. Twelve microsatellite markers carrying the blast resistance gene clearly demonstrated a polymorphic pattern between both parental lines. Among these, two markers, RM206 and RM5961, located on chromosome 11 exhibited the expected 1:1 testcross ratio in the BC2F1 population. The 195 BC2F1 plants inoculated against M. oryzae pathotype P7.2 showed a significantly different distribution in the backcrossed generation and followed Mendelian segregation based on a single-gene model. This indicates that blast resistance in PS2 is governed by a single dominant gene, which is linked to RM206 and RM5961 on chromosome 11. The findings presented in this study could be useful for future blast resistance studies in rice breeding programs.

Abstract
Incidences of altered development and neoplasia of male reproductive organs have increased during the last 50 years, as shown by epidemiological data. These data are associated with the increased presence of environmental chemicals, specifically "endocrine disruptors," that interfere with normal hormonal action. Much research has gone into testing the effects of specific endocrine disrupting chemicals (EDCs) on the development of male reproductive organs and endocrine-related cancers in both in vitro and in vivo models. Efforts have been made to bridge the accruing laboratory findings with the epidemiological data to draw conclusions regarding the relationship between EDCs, altered development and carcinogenesis. The ability of EDCs to predispose target fetal and adult tissues to neoplastic transformation is best explained under the framework of the tissue organization field theory of carcinogenesis (TOFT), which posits that carcinogenesis is development gone awry. Here, we focus on the available evidence, from both empirical and epidemiological studies, regarding the effects of EDCs on male reproductive development and carcinogenesis of endocrine target tissues. We also critique current research methodology utilized in the investigation of EDCs effects and outline what could possibly be done to address these obstacles moving forward.

Abstract
Phosphate limitation as a method to control biofouling of spiral wound reverse osmosis (RO) membranes was studied at a full-scale installation fed with extensively pretreated water. The RO installation is characterized by (i) a low feed channel pressure drop increase and (ii) low biomass concentrations in membrane elements at the installation feed side. This installation contrasted sharply with installations fed with less extensively pretreated feed water (and therefore higher phosphate concentrations) experiencing a high-pressure drop increase and high biomass concentrations in lead elements. Membrane fouling simulator (MFS) studies showed that low phosphate concentrations (approximately 0.3 microg P L(-1)) in the feed water restricted the pressure drop increase and biomass accumulation, even at high substrate (organic carbon) concentrations. In the MFS under ortho-phosphate limiting conditions, dosing phosphonate based antiscalants caused biofouling while no biofouling was observed when acids or phosphonate-free antiscalants were used. Antiscalant dosage could increase both phosphate and substrate concentrations of the water. Therefore, antiscalant selection may be critical for biofouling control. Since no biofouling was observed at low phosphate concentrations, restricting biomass growth by phosphate limitation may be a feasible approach to control biofouling, even in the presence of high organic carbon levels.

Abstract
Human umbilical cord blood (UCB) cells have many advantages as grafts for cell transplantation. Here, we transplant UCB cells into injured liver fibrosis, investigated the hepatic potential of UCB cells both in vitro and in vivo. a CCl4 rat model with liver fibrosis was prepared. Human (UCB) CD34(+) stem cell was separated with MACS (magnetic cell sorting). Cells were cultured with and without hepatic differentiation medium. Rats were divided into 3 groups; group (1): control healthy, group (2): CCl4 injected rats and group 3: CCl4/CD34(+)injected rats with human differentiated and undifferentiated cells through intrahepatic (IH) and intravenous (IV) routes. A significant elevation was detected in serum albumin in CCl4/CD34(+) compared to the CCl4 group (p<0.001). Serum ALT, had a significant decrease of its level after administration of stem cells compared to the CCl4 group (p<0.001). However, it was still significantly higher than control (p<0.001) with no significant difference between the groups that received stem cells. Histopathological examination of liver tissue showed that stem cells have a significant antifibrotic effect. Concerning gene expression, the collagen gene (rat) was highly expressed in the CCl4 group whereas its expression was significantly decreased after administration of stem cells. Human albumin and matrix metalloproteinase (MMP2) genes were expressed in liver tissues in the groups that received stem cells. Highest expression was in the group that received un-differentiated cells I.V. human UCB CD34(+) stem cells can ameliorate liver fibrosis in rats.

Abstract
The study was done to see the changes of placental diameter, thickness and number of cotyledons in eclapmsia. A total 45 placenta, 25 from eclamptic mother and 20 from normal pregnant mother were collected from Gynaecology and Obstetric department of Mymensingh Medical College and Hospital (MMCH). Study was done in Anatomy department of Mymensingh Medical College (MMC). Macroscopic study of the formol saline fixed placentas revealed that, compared to the controls there was trend of less placental diameter in eclamptic group(p=0.0004). Cotyledon number was found to be significantly less in eclampsia (p=0.0001). However there was no significant difference in placental thickness in eclamptic placenta than that of normal group. Statistical significance of difference between two groups was calculated by using Students "t" test. A difference between the two groups was considered to be significant when p<0.005. The morphological changes in placenta are possibly due to reduced uteroplacental blood flow in eclampsia.

Abstract
The study was done to see the relationship of recurrent laryngeal nerves with corresponding inferior thyroid artery with the aim to increase the knowledge regarding variational anatomy in our population. Sixty samples were collected as block dissection of thyroid gland along with the surrounding structures containing the supplying vessels and adjacent nerves from 48 male and 12 female cadavers of different age groups and fixed in 10% formol-saline solution. Fine dissections were carried out to study the toporgaphic relationship of recurrent laryngeal nerves with corresponding inferior thyroid artery. The findings were compared between different age groups and also with the findings of western researchers. In this study, in majority of the cases the recurrent laryngeal nerves were found in their usual location that is posterior to the terminal branches of inferior thyroid artery on the left side and anterior to that artery on the right side. It was important to note that, on both sides recurrent laryngeal nerves were also frequently found to pass in between the terminal branches of inferior thyroid artery.

Abstract
A very tightly controlled expression vector was constructed, which was originally designed as to be able to use any promoter, constitutive or regulated. Moreover, in vector pNH46T1, the repressible P(tac)/P(lac) promoters were used to transcribe genes cloned in the proximal multiple cloning site (MCS), which was flanked by convergent attB and attP sites. The gene of interest was cloned into MCS in the OFF orientation, i.e. facing the promoter(s). In such OFF orientation, the cloned gene could not be expressed, and only its anti-sense mRNA could be produced. Four strong rrnBT1 terminators, in a tandem arrangement and proximal to the N-terminal end of the cloned non-inverted gene, were protecting it from any inadvertent transcription originating in the vector. Moreover, the P(tac)/P(lac) promoters/operators are controlled by the LacI(q)ts and LacI(+) repressor(s) that further reduce the basal gene expression in the uninduced state. When induced, the total vector population is converted to the ON orientation by expression of the Int function that inverts the attB and attP-flanked MCS including the cloned gene. This places the gene under direct control of the P(tac)/P(lac) promoters, and thus results in very high expression. An additional feature is the anti-termination system that consists of the promoter-proximal nutL site and the inducible gene N, whose role in the ON state is to overcome the rrnBT1 terminators and any other adventitiously cloned terminators.

Abstract
Past evaluation research has documented improved nutritional outcomes resulting from participation in the Special Supplemental Nutrition Program for Women, Infants and Children (WIC). However, these evaluations have not examined the program from the clients' perspective, nor have they examined the independent effect of the nutrition education component. The purpose of this study was to quantitatively and qualitatively examine client satisfaction with the nutrition education component of the California WIC program. The methodology consisted of two phases. During phase I of the study (the quantitative component), participants completed Client Satisfaction Surveys immediately following attendance of one nutrition class. During phase II (the qualitative component), four focus groups were conducted. All subjects were participants in the California WIC program. Client Satisfaction Surveys were completed by 2138 participants, and the focus groups included 29 participants. Results from both phases of the study indicated that client satisfaction with the nutrition education component of the California WIC program was high. Between 80% and 95% of participants responded positively to five satisfaction questions, and focus group participants unanimously agreed that the nutrition education was an essential component of the program. Hispanic participants were more likely than non-Hispanic Caucasians, Asians, or African Americans to respond positively to three of the five satisfaction questions. For two of the questions, the frequency of positive responses increased as age increased and decreased as education level increased. A small segment of clients reported some dissatisfaction by responding negatively to one or more of the satisfaction questions (4% to 20% of respondents). Some suggestions for improvement were made by survey respondents. Identification of some WIC participants who are not completely satisfied with the nutrition education that they have received, paired with differences in satisfaction across demographic variables, suggests the need for a personalized approach to WIC nutrition education.

Abstract
We report two cases of hepatocyte neoplasia with extensive deposition of Dubin-Johnson-like pigment in men without Dubin-Johnson syndrome. This pigment has previously been described in hepatocellular carcinoma but not in liver cell adenoma. The tumors of both patients showed some atypical cytologic features, but no frank histologic evidence of malignancy. Long-term follow up for several years showed no evidence of recurrence after limited surgical excision. We conclude that tumors with this structure may be cured by limited surgical excision and should be considered as pigmented liver cell adenomas.

Abstract
OBJECTIVE To access the prospects of daycare pediatric surgery in a developing country like Pakistan in view of economic advantages, parent's acceptability and utilization of hospital resources. METHODS This prospective study was carried out in Karachi from 1st January 1994 to 31st December 1996 in three different private hospitals having optimum operating, anaesthetic and recovery facilities. Selection criteria included general fitness for surgical procedure, not requiring hospitalization, no associated congenital malformation and co-operative parents residing in Karachi. An evening before surgery, all patients were examined thoroughly and detailed instructions for pre-operative fasting and pre-medications were given to the family. Operations were carried out by same surgical team with different set of anesthetists. After surgery and recovery from anesthesia, the children were observed in a holding area adjacent to operating room till fully conscious and alert. Before leaving the hospital, the parents were briefed about post-operative care at home like feeding, ambulation and use of analgesics. A contact telephone number was also provided to the family for any difficulty or emergency. All patients were re-examined 36-48 hours post-operatively in clinic, for any problem at home and the parents were assessed for their attitude toward this modality. RESULTS In 3-year period a total of 368 surgical procedures were carried out of whom 129 operations were done in children under 1-year of age and the youngest patient was one week old with a weight of 2.9 kg. The average age was 2.9 years and average weight was 13 kg. Male:female ratio was 3.6:1. The average operating time was 28 min, average anaesthesia time was 38 min and average recovery time was 17 min, which was not affected by the use of endotracheal tube. Majority of parents managed their children very well at home and only 17% of them called one of the surgeons to inquire about their apprehension at home and all were explained and satisfied. On an average 37% children required two doses of post-operative oral analgesia and 59% returned to normal activity after 24 hours. The overall incidence of complication was 3.6% and there were no deaths or major complications. Only one patient required post surgical hospitalization due to post-operative pneumonia. The mode of management was cost effective and also the parents appreciated the avoidance of hospitalization because of less disruption of their routine work at home and office. CONCLUSION Based on the above experience, we recommended that a variety of common pediatric operations can be done safely as out patients in infants and children, with economic advantages, high parent's acceptability and better utilization of hospital resources without scarifying the quality of health services.
