An assessment of a performance-based management agreement initiative in Ghana's health service.

BACKGROUND: As part of its efforts to improve efficiency, accountability and overall performance, the Ghana Health Service (GHS) introduced annual Performance-based Management Agreements (PMAs) in the year 2013. However, no assessment of this initiative has since been made in order to inform policy and practice. This paper provides an assessment of this policy initiative from the perspective of managers at various levels of service implementation. METHODS: Mixed methods were employed. Questionnaires were administered to managers through an online survey (using Google forms). Descriptive and inferential statistical methods were used to analyze and present quantitative results while qualitative data was analyzed via thematic analysis. RESULTS: The content and objectives of the PMAs were observed to be comprehensive and directed at ensuring high performance of directorates. Targets of PMAs were found to be aligned with overall health sector objectives and priorities. The directors felt PMAs were useful for delegating task to subordinates. PMAs were also found to increase commitment and contributed to improving teamwork and prudent use of resources. However, PMAs were found to lack clear implementation strategies and were not backed by incentives and sanctions. Also, budgetary allocations did not reflect demands of PMAs. Furthermore, directors at lower levels were not adequately consulted in setting PMAs targets as such district specific challenges and priorities are not usually factored into the process. Insufficient training of staff and lack of requisite staff were key challenges confronting the implementation of PMAs in most directorates. Weak monitoring and evaluation was also observed to significantly affect the success of PMAs. CONCLUSION: There is the need to address the weaknesses and improve on the existing strengths identified by this assessment in order to enhance the effectiveness of PMAs utilization in the Ghana health service.

Mycothiol acetyltransferase (Rv0819) of Mycobacterium tuberculosis is a potential biomarker for direct diagnosis of tuberculosis using patient serum specimens.

Mycobacterium tuberculosis infection constitutes a global threat that results in significant morbidity and mortality worldwide. Efficient and early diagnosis of tuberculosis (TB) is of paramount importance for successful treatment. The aim of the current study is to investigate the mycobacterial mycothiol acetyltransferase Rv0819 as a potential novel biomarker for the diagnosis of active TB infection. The gene encoding Rv0819 was cloned and successfully expressed in Escherichia coli. The recombinant Rv0819 was purified using metal affinity chromatography and was used to raise murine polyclonal antibodies against Rv0819. The raised antibodies were employed for direct detection of Rv0819 in patient serum samples using dot blot assay and competitive enzyme-linked immunosorbent assay (ELISA). Serum samples were obtained from 68 confirmed new TB patients and 35 healthy volunteers as negative controls. The dot blot assay showed sensitivity of 64·7% and specificity of 100%, whereas the competitive ELISA assay showed lower sensitivity (54·4%) and specificity (88·57%). The overall sensitivity of the combined results of the two tests was found to be 89·7%. Overall, the mycobacterial Rv0819 is a potential TB serum biomarker that can be exploited, in combination with other TB biomarkers, for efficient and reliable diagnosis of active TB infection. SIGNIFICANCE AND IMPACT OF THE STUDY: The early and accurate diagnosis of tuberculosis infection is of paramount importance for initiating treatment and avoiding clinical complications. Most current diagnostic tests have poor sensitivity and/or specificity and in many cases they are too expensive for routine diagnostic testing in resource-limited settings. In the current study, we examined a novel mycobacterial serum biomarker, namely mycothiol acetyltransferase Rv0819. The antigen was detectable in serum specimens of a significant number of tuberculosis patients. This article proves the importance of Rv0819 and paves the way towards its future use as a useful diagnostic marker for tuberculosis infection.

Mandibular kinematic changes after unilateral cross-bite with lateral shift correction.

The aim of this randomised prospective study was to evaluate the effects of slow maxillary expansion with expansion plates and Hyrax expanders on the kinematics of the mandible after cross-bite correction. Thirty children (15 boys and 15 girls), aged 7·1-11·8, with unilateral cross-bite and functional shift were divided into two groups: expansion plate (n = 15) and Hyrax expander (n = 15). Thirty children with normal occlusion (14 boys and 16 girls, aged 7·3-11·6) served as control group. The maximum vertical opening, lateral mandibular shift (from maximum vertical opening to maximum intercuspation, from rest position to maximum intercuspation and from maximum vertical opening to rest position) and lateral excursions were recorded before and 4 months after treatment. After treatment, the expansion plate group showed a greater lateral shift from rest position to maximum intercuspation than did the control group. The expansion plate patients also presented greater left/contralateral excursion than did the control group. Comparisons of changes after treatment in the cross-bite groups showed significant decreases in the lateral shift from the maximum vertical opening to maximum intercuspation and from the maximum vertical opening to rest position, a significant increase in the homolateral excursion and a significant decrease in the contralateral excursion in the Hyrax expander group, whereas no significant differences were found in the expansion plate group. In conclusion, the Hyrax expander showed better results than did the expansion plate. The Hyrax expander with acrylic occlusal covering significantly improved the mandibular lateral shift and normalised the range of lateral excursion.

Mesenchymal stem cells in oral reconstructive surgery: a systematic review of the literature.

This study evaluated clinical outcomes following intraoperative use of adult mesenchymal stem cells (MSCs) in various oral reconstructive procedures. PubMed was searched without language restrictions from 2000 to 2011 using the search words stem cell, oral surgery, tissue engineering, sinus lift, bone regeneration and combinations of these. Inclusion criteria were intraoperative use of MSCs in the study design. Reference lists of the articles found were searched for other related studies. Eighteen clinical trials using MSCs for sinus augmentation were found: five case reports on the repair of large bony defects and six studies on ridge augmentation and healing of alveolar sockets after third molar extraction. The findings suggest that MSCs are capable of producing in vivo bone, re-establishing lost tissue and facilitating placement of dental implants. Use of MSCs would reduce patient morbidity because of a less stressful harvesting technique than that of autogenous bone. The majority of clinical trials indicate that MSCs can produce bone in vivo. However, a satisfactory outcome was not seen in all studies, and due to the diversity of study designs, a 'golden approach' cannot be determined. Before use of MSCs can be considered as a first-choice treatment, more predictable outcomes and better long-term prognoses need to be established. Conventional bone grafting remains the gold standard.

Water productivity and growth parameters of Fawn-tall fescue and Tekapo-orchard grass under deficit irrigation in arid zones.

This study aimed to determine the drought stress response of Fawn-tall fescue and Tekapo-orchard grass and investigate a drought stress resistance marker. Grass genotypes were grown under four Irrigation treatments I1 equivalent to 0.3 standard crop evapotranspiration (ETc), I2 equivalent to 0.65 ETc, I3 equivalent to 0.75 ETc, and I4 equivalent to 1.2 ETc. Plant height, fresh weight, dry weight were measured and the Water productivity (WP) were calculated. The results showed a reduction in the growth of both grass genotypes as the drought stress increased as indicated by the shorter plants and reduction in fresh and dry weight. However, the WP results showed that the Fawn-tall fescue endured the drought stress better than the Tekapo-orchard grass as indicated by the constant values of the plant WP across the tested irrigation treatments. The results was confirmed by the amplification of dehydrin genes where Fawn-tall fescue was found to be homozygous for dehydrin genes.

Adherence to Good Pharmacy Practices by Community Pharmacies in Lebanon and Opportunities for Quality Improvement: It is Time to Act.

Purpose: Good pharmacy practice is an important standard that highlight the quality of services in community pharmacies. In 2018, The Order of Pharmacists in Lebanon (OPL) published their own good pharmacy practices (GPP) guidelines. The need exists for investigational studies to assess GPP implementation status and the professional conduct of on-site staff towards these standards. Methods: Data collection was carried out between February and August 2020 using a questionnaire covering: Socio-demographic variables; Indicator A (Attitude of the Community Pharmacists); Indicator B (Services and Facilities); Indicator C (Dispensing); Indicator D (Storage). Data analysis were performed on SPSS version 25, T-Test and ANOVA were used. A significant p value of <0.001, 95% confidence interval and variables with missing data counting less than 10% were considered. Results: A total of 211 staffers from pharmacies were enrolled in the study, each representing one community pharmacy. The mean percent of adherence to GPP standards by community pharmacies in the South of Lebanon was below the recommended threshold of 75%. Only 65.09% adhered to all tested indicators (27% to Indicator A, 56.91% to Indicator B, 68.61% to Indicator C, 66.31% to Indicator D). Higher indicators were seen among providers who were aware of OPL standards (OR = 4.021), female (OR= 2.011) and being a licensed pharmacist (OR=3.506). Cronbach alpha of the overall score was 0.615. Conclusion: Further steps shall be taken to improve the compliance to GPP standards. Steps shall include, identification of the core standards, such as dispensing, provision of adequate information, monitoring of storage conditions, and ensuring the presence of a licensed pharmacist. It is highly recommended that the OPL and the Ministry of Public Health develop a "Self-assessment tool" and an efficient training program to increase community Pharmacists' awareness status. Regular assessment shall be carried to monitor the progress overtime.

Quantification of prefrontal cortical neuronal ensembles following conditioned fear learning in a Fos-LacZ transgenic rat with photoacoustic imaging in Vivo.

Understanding the neurobiology of complex behaviors requires measurement of activity in the discrete population of active neurons, neuronal ensembles, which control the behavior. Conventional neuroimaging techniques ineffectively measure neuronal ensemble activity in the brain in vivo because they assess the average regional neuronal activity instead of the specific activity of the neuronal ensemble that mediates the behavior. Our functional molecular photoacoustic tomography (FM-PAT) system allows direct imaging of Fos-dependent neuronal ensemble activation in Fos-LacZ transgenic rats in vivo. We tested four experimental conditions and found increased FM-PAT signal in prefrontal cortical areas in rats undergoing conditioned fear or novel context exposure. A parallel immunofluorescence ex vivo study of Fos expression found similar findings. These findings demonstrate the ability of FM-PAT to measure Fos-expressing neuronal ensembles directly in vivo and support a mechanistic role for the prefrontal cortex in higher-order processing of response to specific stimuli or environmental cues.

Comparison of off-the-shelf ß-tricalcium phosphate implants with novel resorbable 3D printed implants in mandible ramus of pigs.

Facial reconstructive surgery has already implemented the use of 3D printed Patient Specific Implants derived from CAD/CAM-based technologies as an alternative to preformed bone graft substitutes. 3D-printed patient-specific implants derived from CAD/CAM-based technologies are used in facial reconstructive surgery as an alternative to preformed bone graft substitutes. However, to minimize the invasiveness and long-term adverse effects of surgical interventions, the implant needs to exhibit exact fitting, porosity, density, and volume and be made from resorbable materials that allow ingrowth and formation of new bone tissue. Therefore, we present this pilot study using 3D-printed implants consisting of pure ß-TCP, produced using a novel technique that assures these properties. Eight pigs received 3D-printed truncated porous cone bone implants paired with either an off-the-shelve a chronOS (DePuy Synthes chronOS Vivify Preforms) preformed block (n = 4) or a no-implant void (n = 4) in a surgically created defect on each side of the angle of the mandible. After 6 months, CT data showed that all 3D-printed implants performed as well as did the off-the-shelve implants, with predicted osteointegration medially and laterally and with minimal gapping between the implants and native bone. The CT findings were confirmed by histological analysis that revealed that the 3D-printed implants together with the off-the-shelve implants were almost complete resorbed. Much of the resorbed volume had been replaced by vascularized compact bone, and fusion between newly formed bone and native bone was observed in all implants, further indicating that the 3D-printed implants and off-the-shelve implants performed equally well. Only soft tissue developed in the void control sites. Further studies are needed to confirm these initial findings.

The current trends and challenges towards good community pharmacy practice and the way forward.

Background: The practice of pharmacy continues to evolve. Comprehensive research to monitor and assess the development of the practice is needed. Good Pharmacy Practices (GPP) have been adopted by many countries to enhance the quality of services. Little information is available concerning how pharmacy practices are being implemented in developing countries. Lebanon being a developing country is a good example where community pharmacy practice doesn't follow clear guidelines and no evidence of good clinical practice. Objectives: This study aims to highlight GPP implementation, to identify obstacles impeding implementation, and to suggest how its application could be facilitated in Lebanon. Methods: The review included studies published in English during the last five years covering aspects of pharmacy practice in relation to GPP standards. The search excluded research related to hospital pharmacy practice and primary health care centers since they have their own quality standards. Results: The research identified 20 recent studies that covered aspects of community pharmacy practice in Lebanon in relation to GPP standards. Eight of the studies related to research and professional development,5 related to the provision of medicines,4 related to interaction and communication,1 related to trainees,1 related to pharmacotherapy monitoring, and 1 related to documentation systems. An additional 6 studies provided insight into factors that affect the pharmacy practice in general. It is apparent that the pharmacy practice would benefit if pharmacists were better supported with financial incentives and a readjustment of their working conditions as this would have a positive impact on their productivity, job satisfaction, and overall well-being. The review indicated that the standard of research and professional development was the most studied topic and it was recommended that pharmacists develop their research capabilities. It was observed that there is a tendency towards implementing Continuous Education for pharmacists and obstacles primarily included work and family commitments, lack of interest, lack of time, difficulties in commuting, and lack of competence in the use of technology. This standard is aligned with the FIP's developmental goal of continuing professional development strategies. The search also identified only one pilot study to assess GGP compliance among community pharmacies in Lebanon. This pilot study was limited and showed low adherence of community pharmacies in Lebanon to GPP standards.Barriers to implementation are lack of enforcing laws,inadequate dissemination of the standards among the community pharmacists, poor public perception, and the financial and soscioeconomically crisis facing Lebanon. Conclusion: Collaborated efforts are needed to implement GPP standards in Lebanon.It is recommended to undergo training and awareness sessions to community pharmacists thus enhancing their commitment and motivation. It is also recommended to establish key performance indicators to monitor the implementation. Indicators should include structure indicators for regulating the storage of medications, process indicators for regulating the dispensing, and outcome indicators for reporting patient safety incidents, measuring public satisfaction and the provision and use of medicines.These recommendations can be used by Health authorities and Pharmacy educational institutions in Lebanon and in all similar low-income countries.

Public views of community pharmacy services during the COVID-19 pandemic: a national survey.

OBJECTIVE: To assess public opinion about community pharmacy services in Lebanon during the COVID-19 pandemic. METHOD: A cross-sectional study using an online questionnaire was conducted between April and August of 2021. A link was shared randomly among the Lebanese population using WhatsApp and Facebook. Public perceptions were explored within 3 different indicators: general services (B) dispensing (C), and storage (D). Chi-square, Student's test and ANOVA tests were used. p < 0.05 was considered statistically significant. RESULTS: Out of 491 responses, only 9.6% scored above the 75th percentile (19.3% for the general services, 2.4% for dispensing indicator and 12.6% for storage indicator). The main concerns focused on lack of medication and reduced opening hours; however, 67.1% of respondents preferred consulting the community pharmacist instead of visiting primary health care centers, doctor's private clinic and hospitals. Higher mean values of indicators B, C and in the overall indicator were significantly found in the presence of a pharmacist compared to the support pharmacy workforce. CONCLUSION: The overall public perception was inadequate. Significant difference in terms of quality of services was detected in the presence and absence of a community pharmacist during the crisis. It is recommended that the Order of Pharmacist of Lebanon (OPL) and the Ministry of Public Health (MOPH) undergo further steps mainly to enforce the laws concerning dispensing and storage indicators, improve the services in terms of extending the opening hours, ensure the availability of medicines and increase public awareness.

A variety of cells in addition to stem cells, as well as advances in materials science to meet specific requirements for bone and soft tissue regeneration by addition of bioactive molecules, are discussed.

Snorc is a novel cartilage specific small membrane proteoglycan expressed in differentiating and articular chondrocytes.

OBJECTIVE: Maintenance of chondrocyte phenotype is a major issue in prevention of degeneration and repair of articular cartilage. Although the critical pathways in chondrocyte maturation and homeostasis have been revealed, the in-depth understanding is deficient and novel modifying components and interaction partners are still likely to be discovered. Our focus in this study was to characterize a novel cartilage specific gene that was identified in mouse limb cartilage during embryonic development. METHODS: Open access bioinformatics tools and databases were used to characterize the gene, predicted protein and orthologs in vertebrate species. Immunohistochemistry and mRNA expression methodology were used to study tissue specific expression. Fracture callus and limb bud micromass culture were utilized to study the effects of BMP-2 during experimental chondrogenesis. Fusion protein with C-terminal HA-tag was expressed in Cos7 cells, and the cell lysate was studied for putative glycosaminoglycan attachment by digestion with chondroitinase ABC and Western blotting. RESULTS: The predicted molecule is a small, 121 amino acids long type I single-pass transmembrane chondroitin sulfate proteoglycan, that contains ER signal peptide, lumenal/extracellular domain with several threonines/serines prone to O-N-acetylgalactosamine modification, and a cytoplasmic tail with a Yin-Yang site prone to phosphorylation or O-N-acetylglucosamine modification. It is highly conserved in mammals with orthologs in all vertebrate subgroups. Cartilage specific expression was highest in proliferating and prehypertrophic zones during development, and in adult articular cartilage, expression was restricted to the uncalcified zone, including chondrocyte clusters in human osteoarthritic cartilage. Studies with experimental chondrogenesis models demonstrated similar expression profiles with Sox9, Acan and Col2a1 and up-regulation by BMP-2. Based on its cartilage specific expression, the molecule was named Snorc, (Small NOvel Rich in Cartilage). CONCLUSION: A novel cartilage specific molecule was identified which marks the differentiating chondrocytes and adult articular chondrocytes with possible functions associated with development and maintenance of chondrocyte phenotype.

Gold(I)-catalyzed Claisen rearrangement of allenyl vinyl ethers; synthesis of substituted 1,3-dienes.

Synthesis of substituted 1,3-dienes was achieved via gold(I)-catalyzed Claisen rearrangement of allenyl vinyl ethers. The N-heterocyclic carbene gold chloride catalyst (IPrAuCl) was superior in terms of activity and selectivity and afforded the 3,3-product in excellent yields. A proposed cation-π inter-action played a significant role in affecting the reaction rate.

Needlestick injuries among health care workers of University of Alexandria Hospitals.

The aims of this cross-sectional study were to investigate the prevalence and circumstances of needlestick injury (NSI) among heath care workers at University of Alexandria teaching hospitals and to assess the effectiveness of the existing control measures and standard precautions. Data were obtained by anonymous, self-reporting questionnaire from 645 nurses, physicians and ancillary staff in 2007. Around two-thirds of workers (67.9%) had suffered at least 1 NSI in the last 12 months. High-risk patients (with history of HIV, hepatitis B virus or, hepatitis C virus infection or injecting drug use) were involved in 8.2% of injuries. On evaluating the effectiveness of existing control measures, significant protective factors against NSI were: using devices with safety features (OR 0.41), adherence to infection control guidelines (OR 0.42), training in injection safety (OR 0.14), comfortable room temperature (OR 0.32) and availability of a written protocol for prompt reporting (OR 0.37).

Plaque Composition as a Predictor of Plaque Ulceration in Carotid Artery Atherosclerosis: The Plaque At RISK Study.

BACKGROUND AND PURPOSE: Plaque ulceration is a marker of previous plaque rupture. We studied the association between atherosclerotic plaque composition at baseline and plaque ulceration at baseline and follow-up. MATERIALS AND METHODS: We included symptomatic patients with a carotid stenosis of <70% who underwent MDCTA and MR imaging at baseline (n = 180). MDCTA was repeated at 2 years (n = 73). We assessed the presence of ulceration using MDCTA. Baseline MR imaging was used to assess the vessel wall volume and the presence and volume of plaque components (intraplaque hemorrhage, lipid-rich necrotic core, and calcifications) and the fibrous cap status. Associations at baseline were evaluated with binary logistic regression and reported with an OR and its 95% CI. Simple statistical testing was performed in the follow-up analysis. RESULTS: At baseline, the prevalence of plaque ulceration was 27% (49/180). Increased wall volume (OR = 12.1; 95% CI, 3.5-42.0), higher relative lipid-rich necrotic core (OR = 1.7; 95% CI, 1.3-2.2), higher relative intraplaque hemorrhage volume (OR = 1.7; 95% CI, 1.3-2.2), and a thin-or-ruptured fibrous cap (OR = 3.4; 95% CI, 1.7-6.7) were associated with the presence of ulcerations at baseline. In 8% (6/73) of the patients, a new ulcer developed. Plaques with a new ulceration at follow-up had at baseline a larger wall volume (1.04 cm3 [IQR, 0.97-1.16 cm3] versus 0.86 cm3 [IQR, 0.73-1.00 cm3]; P = .029), a larger relative lipid-rich necrotic core volume (23% [IQR, 13-31%] versus 2% [IQR, 0-14%]; P = .002), and a larger relative intraplaque hemorrhage volume (14% [IQR, 8-24%] versus 0% [IQR, 0-5%]; P < .001). CONCLUSIONS: Large atherosclerotic plaques and plaques with intraplaque hemorrhage and lipid-rich necrotic cores were associated with plaque ulcerations at baseline and follow-up.

Direct measurement of neuronal ensemble activity using photoacoustic imaging in the stimulated Fos-LacZ transgenic rat brain: A proof-of-principle study.

Measuring neuroactivity underlying complex behaviors facilitates understanding the microcircuitry that supports these behaviors. We have developed a functional and molecular photoacoustic tomography (F/M-PAT) system which allows direct imaging of Fos-expressing neuronal ensembles in Fos-LacZ transgenic rats with a large field-of-view and high spatial resolution. F/M-PAT measures the beta-galactosidase catalyzed enzymatic product of exogenous chromophore X-gal within ensemble neurons. We used an ex vivo imaging method in the Wistar Fos-LacZ transgenic rat, to detect neuronal ensembles in medial prefrontal cortex (mPFC) following cocaine administration or a shock-tone paired stimulus. Robust and selective F/M-PAT signal was detected in mPFC neurons after both conditions (compare to naive controls) demonstrating successful and direct detection of Fos-expressing neuronal ensembles using this approach. The results of this study indicate that F/M-PAT can be used in conjunction with Fos-LacZ rats to monitor neuronal ensembles that underlie a range of behavioral processes, such as fear learning or addiction.

MAPKs are essential upstream signaling pathways in proteolytic cartilage degradation--divergence in pathways leading to aggrecanase and MMP-mediated articular cartilage degradation.

OBJECTIVES: Matrix metalloproteinases (MMPs) and aggrecanases are essential players in cartilage degradation. However, the signaling pathways that results in MMP and/or aggrecanase synthesis and activation are not well understood. We investigated the molecular events leading to MMP- and aggrecanase-mediated cartilage degradation. METHODS: Cartilage degradation was induced in bovine articular cartilage explants by oncostatin M (OSM) and tumor necrosis factor (TNF), in the presence or absence of specific inhibitors of the mitogen-activated protein kinases (MAPKs) P38, P44/42 and Src family. Toxicity was followed by the AlamarBlue colorimetric assay. MMP-activity was assessed using a fluorescent substrate assay and MMP-9 and -2 activities by gelatinase zymography. MMP-mediated collagen type II degradation and MMP as well as aggrecanase-mediated aggrecan degradation was investigated with specific ELISA and hydroxyproline release by standard methods. The findings were verified by immunohistochemistry and histology. RESULTS: Stimulation of cartilage degradation by OSM+TNF resulted in 100-fold induction of CTX-II release (P<0.01). This was dose-dependently inhibited by MAPK P38 inhibitors and by the MAPK P44/42 inhibitors. MMP-activity and expression was significantly decreased, as evaluated by cleavage of fluorescence MMP-substrate and zymography. Immunohistochemistry confirmed these findings. Interestingly, only the P44/42 inhibitors abrogated aggrecanase-mediated aggrecan degradation. CONCLUSION: We found that inhibition of MAPK P38, P44/42 and Src family abrogated proteolytic cartilage degradation by blocking MMP synthesis and activity. However, only MAPK P44/42 was essential for aggrecanase-mediated aggrecan degradation. These data suggest that various aspects of cartilage degradation can be targeted independently by inhibiting specific upstream signaling pathway.

Gender differences in factors associated with patients' decisions to seek treatment for urinary incontinence in Alexandria, Egypt.

The objective of this descriptive, hospital-based comparative cross-sectional survey was to determine gender differences in factors associated with patients' decisions to seek treatment for urinary incontinence (Ul). Using an interview questionnaire, data were collected from 353 patients attending clinics at hospitals in Alexandria, Egypt. There were differences between males and females regarding specific psychosocial factors motivating health care seeking behaviour. Women had fewer hospital admissions and hospital days and less use of diagnostic procedures and surgery. More women suffered from at least one negative impact on their social lives compared to men. The impact of symptoms on quality of life appeared to be the main trigger for seeking help for UI in both men and women.

Novel 6,8-dibromo-4(3H)-quinazolinone derivatives of promising anti-inflammatory and analgesic properties.

A new series of the title compounds incorporated into diverse N and O heterocyclic moieties of pharmacoavailability as anti-inflammatory and analgesic agents, were synthesized starting with 6,8-dibromo-2-phenyl-4H-3,1-benzoxazin-4-one (I) by its fusion with p-aminoacetophenone to give the new intermediate compound, 6,8-dibromo-2-phenyl-3-(4-acetylphenyl)-4(3H)-quinazolinone (II). The one pot reaction of II with the appropriate aromatic aldehydes and anhyd. ammonium acetate in the presence of either ethyl cyanoacetate or malononitrile afforded the corresponding 2(1H)-pyridones III or 2(1H)-iminopyridines IV, respectively, while its reaction with malononitrile and aromatic aldehydes in piperidine gave 2-aminopyrans V. Also, reaction of the acetyl derivative II with aromatic aldehydes afforded the corresponding 1,3-propen-1-one derivatives VI which underwent cyclization with hydrazine to give the corresponding pyrazolines VII and with urea and/or thiourea to give the corresponding tetrahydropyrimidin-2-ones and/or tetrahydropyrimidin-2-thiones VIII. Some representative examples of the new compounds showed promising anti-inflammatory and analgesic activities in experimental animals.

Mixed cation Ag2S-Tl2S-GeS2 glasses: macroscopic properties and Raman scattering studies.

Mixed cation Ag2S-Tl2S-GeS2 glasses containing 40 and 50 mol% of metal sulfide have been synthesized and analyzed for the first time using thermal analysis, conductivity measurements and Raman spectroscopy. The composition dependences of the ionic conductivity and glass transition temperature T g showed the presence of classical mixed cation effect with the minimum of both glass transition temperature and room temperature conductivity and the activation energy maximum centered at r = Ag/(Tl + Ag) ≈ 0.2. Raman spectroscopy measurements reveal that the structure of the mixed glasses is not a simple mixture of the end-members, pure thallium (r = 0) and silver (r = 1) thiogermanates. The edge-sharing ES-Ge2S6 dimers and corner-sharing CS-Ge n S3n+1 (n = 2 or 3) oligomers disappear more quickly than is predicted by the stoichiometry relations. The systematic evolution of the vibrational properties as a function of the silver fraction r also suggests that the both cations are not separated spatially in the glass network but rather located in close proximity to each other.
