Abstract
Systematic assessments of species extinction risk at regular intervals are necessary for informing conservation action1,2. Ongoing developments in taxonomy, threatening processes and research further underscore the need for reassessment3,4. Here we report the findings of the second Global Amphibian Assessment, evaluating 8,011 species for the International Union for Conservation of Nature Red List of Threatened Species. We find that amphibians are the most threatened vertebrate class (40.7% of species are globally threatened). The updated Red List Index shows that the status of amphibians is deteriorating globally, particularly for salamanders and in the Neotropics. Disease and habitat loss drove 91% of status deteriorations between 1980 and 2004. Ongoing and projected climate change effects are now of increasing concern, driving 39% of status deteriorations since 2004, followed by habitat loss (37%). Although signs of species recoveries incentivize immediate conservation action, scaled-up investment is urgently needed to reverse the current trends.

Abstract
BACKGROUND Genital HPV infection is recognized worldwide as one of the most common, if not the most common, sexually transmitted infection. Several studies have shown a higher prevalence of HPV infection in women living with HIV (WLWH). We aimed to determine the prevalence of HPV, the circulating genotypes, and its association with risk factors among Algerian WLHIV. METHODS Cervical specimens were collected from 100 WLHIV. The detection of HPV infection was performed by Roche Linear Array test. RESULTS The overall prevalence of HPV infection was determined at 32%, all including high risk HPV (HR-HPV). We found a great diversity of HR-HPV genotypes, the most common individually were HPV52, HPV16, HPV18 and HPV58, The highest prevalence was found in groups of genotype 52, 25%. HPV16 and 18 were less common (16%). Cervical cytology was abnormal in 66% (81.3% in the HPV + population), with a predominance of inflammatory lesions (75% HPV +), The most important determining risk factor for HPV infection in this series was a low CD4 T cell count <200/mm3 found in 72% of the HPV positive participants. CONCLUSION Our study is an initial database, to be completed by a multicenter study to determine the most frequent genotypes in Algerian WLHIV, in order to discuss the introduction of the vaccine against HPV in Algeria, especially among WLHIV.

Abstract
The lack of information regarding biodiversity status hampers designing and implementing conservation strategies and achieving future targets. Northern Pakistan consists of a unique ecoregion mosaic which supports a myriad of environmental niches for anuran diversity in comparison to the deserts and xeric shrublands throughout the rest of the country. In order to study the niche suitability, species overlap and distribution patterns in Pakistan, we collected observational data for nine anuran species across several distinct ecoregions by surveying 87 randomly selected locations from 2016 to 2018 in Rawalpindi District and Islamabad Capital Territory. Our model showed that the precipitation of the warmest and coldest quarter, distance to rivers and vegetation were the greatest drivers of anuran distribution, expectedly indicating that the presence of humid forests and proximity to waterways greatly influences the habitable range of anurans in Pakistan. Sympatric overlap between species occurred at significantly higher density in tropical and subtropical coniferous forests than in other ecoregion types. We found species such as Minervarya spp., Hoplobatrachus tigerinus and Euphlyctis spp. preferred the lowlands in proximal, central and southern parts of the study area proximal to urban settlements, with little vegetation and higher average temperatures. Duttaphrynus bengalensis and D. stomaticus had scattered distributions throughout the study area with no clear preference for elevation. Sphaerotheca pashchima was patchily distributed in the midwestern extent of the study area as well as the foothills to the north. Microhyla nilphamariensis was widely distributed throughout the study area with a preference for both lowlands and montane terrain. Endemic frogs (Nanorana vicina and Allopaa hazarensis) were observed only in locations with higher elevations, higher density of streams and lower average temperatures as compared to the other seven species sampled. It is recommended to provide legal protection to amphibians of Pakistan, especially endemic species, through revision in the existing wildlife laws. We suggest studying the effectiveness of existing amphibian tunnels and corridors or designing new ones tailored to the needs of our species to prevent their local extinction due to ongoing or proposed urban development which might affect their dispersal and colonization.

Abstract
BACKGROUND: Streptomyces sp. from Indonesian soil have not been explored and isolated to find new strains as a source of antibiotics for the treatment of tuberculosis (TB) disease.
AIM: In this study, the effect of Streptomyces spp. from Lapindo mud in Sidoarjo, Indonesia be observed, to find out whether Streptomyces spp. has anti-TB activity.
METHODS: The primers Strep F; 5-AGAGTTTGAT CCTGKGTCAG-3 and Strep R; 5-AAGGGAG GTGATCCAKKGKGA-3 were used in polymerase chain reaction amplification of the 16S rRNA gene against Streptomyces strains. The anti-TB activity of Streptomyces sp. was determined by broth dilution method using Middlebrook 7H9 media.
RESULTS: The results showed that new types of Streptomyces spp., namely, Streptomyces A, Streptomyces D, Streptomyces Ea, Streptomyces Ep, Streptomyces I, Streptomyces F, and Streptomyces G from garbage dump soils. This result also showed that the activity of Streptomyces I, Streptomyces F, and Streptomyces G could inhibit the Mycobacterium TB growth by with inhibitory zones, respectively, 2 ± 0.3; 8 ± 0.7 and 15 ± 0.9mm, while Streptomyces A, Streptomyces D, Streptomyces Ea, and Streptomyces Ep did not inhibit M. TB.
CONCLUSION: Thus, from the results obtained, it can be concluded that Streptomyces extract mainly Streptomyces G has promising anti-TB activity by preliminary in vitro techniques. Therefore, it has the definite potential as a source of compounds that may be developed further into antimycobacterial drugs.

Abstract
We recorded tadpoles of eight anuran species from subtropical scrub and pine forests (District Rawalpindi and Islamabad Capital Territory, Pakistan). These include Duttaphrynus melanostictus, Duttaphrynus stomaticus, Microhyla nilphamariensis, Euphlyctis spp., Minervarya spp., Allopaa hazarensis, Nanorana vicina, and Hoplobatrachus tigerinus. Our results showed that the forest type featuring scrub vegetation, low elevation and warmer climate (day air temperature 30°C, day water temperature 28°C) had more species richness (six of the eight recorded species) while the subtropical pine forest featuring relatively low air (16°C) and water (14°C) temperatures and higher elevation had relatively higher anuran endemism. The Indus Valley Toad is an abundant species throughout scrub forest. Changes in climate resulting in increased temperatures in pine forests could negatively impact endemic species by encouraging the spread of species adapted for warmer temperatures.

Abstract
Endemic anurans are particularly vulnerable to environmental changes, and are susceptible to population declines because of their restricted distribution ranges. The Murree Hills Frog Nanoranavicina and Hazara Torrent Frog Allopaahazarensis are associated with the torrential streams and nearby clear water pools in subtropical chir pine forest and other forest types, at elevations higher than 1000 m in Pakistan. In this study, we have provided data on the extent of movement of these frog species for the first time. We installed radio transmitters on a total of 13 Murree Hills Frogs and 13 Hazara Torrent Frogs during eight consecutive days in September 2017 and 2018. Our results showed that these frogs did not move long distances along the stream or away from the stream into the forest. All the radio-tracked frogs showed movement of < 3 m. We found a significant differences only in the distance moved by Murree Hills Frogs between the two years studied. Based on our findings, we propose a movement paradigm that focuses on conservation implications for these endemic frogs.

Abstract
Wildlife monitoring programs are instrumental for the assessment of species, habitat status, and for the management of factors affecting them. This is particularly important for species found in freshwater ecosystems, such as amphibians, as they have higher estimated extinction rates than terrestrial species. We developed and validated two species-specific environmental DNA (eDNA) protocols and applied them in the field to detect the Hazara Torrent Frog (Allopaa hazarensis) and Murree Hills Frog (Nanorana vicina). Additionally, we compared eDNA surveys with visual encounter surveys and estimated site occupancy. eDNA surveys resulted in higher occurrence probabilities for both A. hazarensis and N. vicina than for visual encounter surveys. Detection probability using eDNA was greater for both species, particularly for A. hazarensis. The top-ranked detection model for visual encounter surveys included effects of both year and temperature on both species, and the top-ranked occupancy model included effects of elevation and year. The top-ranked detection model for eDNA data was the null model, and the top-ranked occupancy model included effects of elevation, year, and wetland type. To our knowledge, this is the first time an eDNA survey has been used to monitor amphibian species in the Himalayan region.

Abstract
Birds are among the best bio-indicators, which can guide us to recognize some of the main conservation concerns in ecosystems. Anthropogenic impacts such as deforestation, habitat degradation, modification of landscapes, and decreased quality of habitats are major threats to bird diversity. The present study was designed to detect anthropogenic causative agents that act on waterbird diversity in Tarbella Dam, Indus River, Pakistan. Waterbird censuses were carried out from March 2019 to February 2020 in multiple areas around the dam. A total of 2990 waterbirds representing 63 species were recorded. We detected the highest waterbird richness and diversity at Pehure whereas the highest density was recorded at Kabbal. Human activity impacts seemed to be the main factor determining the waterbird communities as waterbirds were negatively correlated with the greatest anthropogenic impacts. Waterbirds seem to respond rapidly to human disturbance.

Abstract
Research on amphibians and their conservation have gained worldwide attention, as the group includes the highest number of threatened and Data Deficient species when compared to other vertebrates. However, amphibians have long been neglected in wildlife conservation, management decisions, policy making, and research agendas in Pakistan. In this paper, an annotated checklist of the 21 amphibian species of Pakistan, a key to their identification, and detailed discussions on variation in species, including the genera Minervarya and Sphaerotheca, are provided. We found a statistically significant difference in the morphometric measurements of males but non-significant difference in the females of the two forms (rusty dorsum and dotted dorsum) of S.maskeyi. Some genera, such as Microhyla, Uperodon, Minervarya, Allopaa, Chrysopaa, Euphlyctis, Nanorana, and Sphaerotheca, in Pakistan are in need of additional data for molecular and morphological comparisons with taxa in other South Asian countries. The predicaments of amphibian research in Pakistan are discussed, gaps identified, and suggestions are made. Although the occurrence of chytrid fungus in Pakistan is predicted of low likelihood, a lack of data merits studying the prevalence of the fungus, particularly in the northern regions of the country which exhibit complex and dynamic ecosystems. It is recommended that systematic and coordinated surveys are conducted throughout the country to build a database of species occurrences and distributions. Additionally, the monitoring of wild populations and threat mitigation, as well as appropriate legislation, are suggested as long-term measures. By adopting an inclusive wildlife conservation approach in Pakistan, amphibians could be integrated into wildlife conservation and management efforts.

Abstract
The current study was focused on documentation of amphibian assemblage in North Punjab and Islamabad Capital Territory, Pakistan, by using mitochondrial gene sequences of 16S rRNA. Our study entailed 37% of the known amphibian species of the country. We provided a phylogenetic analysis based on 74 newly generated mitochondrial 16S rRNAs from nine species of genus Microlyla, Duttaphrynus, Allopaa, Nanorana, Sphaerotheca, Minervarya, Hoplobatrachus, and Euphlyctis. We employed the maximum-likelihood inference and Bayesian analysis to assess the taxonomic status of the samples obtained from Pakistan, with respect to other congeneric species from surrounding regions. Our findings confirmed the taxonomic status of South Asian anuran species Duttaphrynus stomaticus, Duttaphrynus melanostictus, Microhyla nilphamariensis, Allopaa hazarensis, Nanorana vicina, Sphaerotheca maskeyi (synonym: S. pashchima), Minervarya pierrei, Hoplobatrachus tigerinus, and Euphlyctis kalasgramensis in Pakistan. We have reported new country records of genus Minervarya ( M. pierrei). Minervarya pierrei was previously misidentified as Fejervarya limnocharis, due to dearth of genetic information. We provided the first genetic records of our endemic species N. vicina. The results revealed the taxonomic placement of N. vicina with respect to its congeners and validated the taxonomic status of N. vicina from its type locality (Murree) for the first time. The findings of the present study also indicated the paraphyletic relationship of A.- hazarensis with Nanorana species. So, based on our phylogenetic inferences, morphological characters, and habitat preferences, validity of generic status of A. hazarensis is undecided. As our data were not enough to resolve this issue, we suggest sequencing of additional mitochondrial and nuclear genes in the future studies to get a better resolution. We recommend carrying out extensive surveys throughout the country for proper scientific documentation of amphibians of Pakistan. Many new species, some of them might be endemic to Pakistan, are expected to be discovered, and taxonomic status of other species would be resolved.

Abstract
This study was conducted to see whether herpetofaunal assemblage differed amongst hiking trails, undisturbed forest and urban areas within the Margalla Hills National Park, Islamabad Capital Territory, Pakistan. Circular plot area-constrained searches (45 plots in each habitat, each plot with an area of 25 m2) were used from March 2018 to July 2019. We recorded seven amphibian species, nine lizard species and six snake species. The species richness of amphibians and lizards was the same in the studied strata, while the detection and encounter rate of snakes was lower in the undisturbed forest and urban areas. The encounter rate of amphibians differed significantly between urban areas and hiking trails/undisturbed forest. The encounter rate and population density of lizards differed significantly between undisturbed forest and urban areas. The most frequently encountered amphibian species along the hiking trail and urban areas was Duttaphrynusstomaticus, with Hoplobatrachustigerinus in undisturbed forest. The most common and frequently encountered lizard species along the hiking trail and urban areas was Hemidactylusbrookii, while the Ophisopsjerdonii was the most frequently seen in undisturbed forest. The most common and frequently encountered snake species along the hiking trail and undisturbed forest was the Indotyphlopsbraminus, while Ptyasmucosa was the most common in urban areas. The subsequent bio-assessment, based on herpetofauna, of the Park revealed good to excellent biotic integrity The Park faces threats including livestock grazing, alien invasive vegetation and human disturbance due to settlements, restaurants and tourism-related activities. While several of these threats have been mitigated since the establishment of the Islamabad Wildlife Management Board, the Park still requires improved management, especially regarding regulating tourism.

Abstract
The larvae of some amphibian species grow and develop more slowly at lower temperature and attain larger body size at the end of metamorphosis, but this is not true for all amphibians. We have for the first time provided empirical data by using a combination of field and lab-based studies with a robust sample size (360 adults, 1000 tadpoles) for Hazara Torrent Frog (Allopaa hazarensis) and Murree Hills Frog (Nanorana vicina). In this study, we examined how tadpoles responded to different temperatures through metamorphosis, body size, developmental complications or deformities, fitness and survival. We found that the tadpoles of A. hazarensis and N. vicina showed the same response to elevated temperatures under laboratory conditions including faster metamorphosis, reduction in the body size, more frequent developmental complications or deformities such as edema and tail kinks, lower fitness and higher mortality at elevated temperatures (>26 °C). The comparison of thermal sensitivity between the two species showed that N. vicina was more sensitive to higher temperatures. Pakistan has been experiencing changes in climatic patterns, and the ecosystems in northern Pakistan are losing biodiversity due to increasing temperature, frequency of drought and intensity of floods. It is feared that these frogs may experience local extinction in future. Our findings contribute to filling the information gap regarding impacts of temperature increase on biodiversity of high altitude forested montane ecosystems and is an important contribution to future studies associating biodiversity and climate change.

Abstract
The genus Nanorana, also called Yunnan Slow Frogs (Frank Ramus 1995), belongs to the family Dicroglossidae. Murree Hills Frog N. vicina, is an endemic species of Southeast Asian uplands in Pakistan and India and was first reported by Stoliczka (1872) from Murree, Punjab Province, Pakistan. Later Rais et al. (2014) recaptured it from its type locality and described morphology of one juvenile female and one adult male. The species is listed as Least Concern in IUCN Red List of Threatened Species while the EDGE (Evolutionarily Distinct and Globally Endangered) score is 2.64. In Pakistan, it is reported from brook water springs and streams of Murree, Galiat (North Punjab), Ayubia (Khyber Pakhtunkhwa), and parts of Azad Jammu and Kashmir (Rais et al. 2014). Although the adult form has been characterized (Khan 2006; Rais et al. 2014), the morphology of the tadpoles have not yet been described. The current study aimed to describe external morphology and morphometry of tadpoles of N. vicina.

Abstract
Background/Objectives Androgen deprivation therapy (ADT) is commonly used for treatment of
prostate cancer, but is associated with side effects such as sarcopenia and
insulin resistance. The role of lifestyle factors such as diet and exercise
on insulin sensitivity and body composition in testosterone-deficient males
is poorly understood. The aim of the present study was to examine the
relationships between androgen status, diet, and insulin sensitivity. Subjects/Methods Middle-aged (11–12-yo) intact and orchidectomized male rhesus
macaques were maintained for two months on a standard chow diet, and then
exposed for six months to a Western-style, high-fat/calorie-dense diet (WSD)
followed by four months of caloric restriction (CR). Body composition,
insulin sensitivity, physical activity, serum cytokine levels, and adipose
biopsies were evaluated before and after each dietary intervention. Results Both intact and orchidectomized animals gained similar proportions of
body fat, developed visceral and subcutaneous adipocyte hypertrophy, and
became insulin resistant in response to the WSD. CR reduced body fat in both
groups, but reversed insulin resistance only in intact animals.
Orchidectomized animals displayed progressive sarcopenia, which persisted
after the switch to CR. Androgen deficiency was associated with increased
levels of interleukin-6 and macrophage-derived chemokine (CCL22), both of
which were elevated during CR. Physical activity levels showed a negative
correlation with body fat and insulin sensitivity. Conclusion Androgen deficiency exacerbated the negative metabolic side effects
of the WSD, such that CR alone was not sufficient to improve altered insulin
sensitivity, suggesting that ADT patients will require additional
interventions to reverse insulin resistance and sarcopenia.

Abstract
BACKGROUND Global brain abnormalities such as brain volume loss and grey- and white-matter deficits are consistently reported in first-episode schizophrenia patients and may already be detectable in the very early stages of the illness. Whether these changes are dependent on medication use or related to intelligence quotient (IQ) is still debated. METHOD Magnetic resonance imaging scans were obtained for 20 medication-naive patients with first-episode schizophrenia and 26 matched healthy subjects. Volume measures of total brain grey and white matter, third and lateral ventricles and cortical thickness/surface were obtained. Differences between the groups were investigated, taking into account the effect of intelligence. RESULTS Medication-naive patients showed statistically significant reductions in whole-brain volume and cerebral grey- and white-matter volume together with lateral ventricle enlargement compared to healthy subjects. IQ was significantly lower in patients compared to controls and was positively associated with brain and white-matter volume in the whole group. No significant differences in cortical thickness were found between the groups but medication-naive patients had a significantly smaller surface in the left superior temporal pole, Heschl's gyrus and insula compared to controls. CONCLUSIONS Our findings suggest that brain volume loss is present at illness onset, and can be explained by the reduced surface of the temporal and insular cortex. These abnormalities are not related to medication, but IQ.

Abstract
PURPOSE Brucellosis is a major ubiquitous zoonosis transmitted from livestock to humans. It is a public health problem in developing countries. Between 2003 and 2005, the incidence of brucellosis in Algeria showed a 181% increase from 8.79 to 24.71. Between 2005 and 2007, the incidence remained almost stable. The estimated mean incidence of neurobrucellosis is 4% with clinical manifestations that are variable and often multi-focal in the same patient. The purpose of this retrospective study is to describe 5 cases of neurobrucellosis managed in our department between 2001 and 2007. MATERIALS AND METHODS It was a retrospective study 5 patients. There were 2 women and 3 men with a mean age of 20 years. RESULTS Neurological involvement occurred immediately in all patients. Clinical manifestations were variable with meningoencephalitis in 2, meningoencephalitis associated with a polyperipheral neuropathy in 1, meningomyeloradiculitis in 1, and acute diffuse encephalitis in 1. Definitive diagnosis was based on isolation of bacteria from a blood specimen in 1 case and detection of antibodies in blood and cerebrospinal fluid in 4. All patients were treated using a combination of 3 of the following 4 drugs: doxycycline, rifampicine, cotrimoxazole and aminoside. Treatment was associated with corticosteroid therapy in 3 cases. DISCUSSION Neurobrucellosis can affect any part of the nervous system and can mimic any neurological disease. Early detection and treatment is the only predictor of favorable outcome of neurobrucellosis, but there is no standardized treatment protocol. Neurobrucellosis should be included in differential diagnosis for any patient presenting central or peripheral neurological manifestations especially in endemic zones.

Abstract
The underlying mechanisms explaining brain volume changes in schizophrenia are not yet understood, but psychosis might be related to these changes. Forty-eight patients with first-episode schizophrenia underwent Magnetic Resonance Imaging brain scanning at inclusion and after five years. An association was found between longer duration of psychosis, larger gray matter volume decrease and larger ventricular volume increase. These findings strongly suggest that psychosis contributes to brain volume reductions found in schizophrenia.

Abstract
Integrin CD18, a component of the LFA-1 complex that also includes CD11a, is essential for Th2, but not Th1, cell homing, but the explanation for this phenomenon remains obscure. In this study, we investigate the mechanism by which Th2 effector responses require the LFA-1 complex. CD11a-deficient T cells showed normal in vitro differentiation and function. However, Th2 cell-dependent allergic lung disease was markedly reduced in CD11a null mice and wild-type mice given LFA-1 inhibitors, whereas control of infection with Leishmania major, a Th1-dependent response, was enhanced. In both disease models, recruitment of IL-4-, but not IFN-gamma-secreting cells to relevant organs was impaired, as was adhesion of Th2 cells in vitro. These diverse findings were explained by the markedly reduced expression of CD29, an alternate homing integrin, on Th2, but not Th1, cells, which precludes Th2 homing in the absence of CD11a. Thus, murine Th1 and Th2 cells use distinct integrins for homing, suggesting novel opportunities for integrin-based therapeutic intervention in diverse human ailments influenced by Th2 cells.

Abstract
To understand the integrin requirements of T-helper (T(H)) effector subsets, we investigated the contribution of CD18 (beta(2) integrin) to T(H)1 and T(H)2 function in vitro and in relevant disease models. CD18-deficient (Itgb2(-/-)) T cells showed largely normal in vitro function. Compared with wild-type mice, Itgb2(-/-) mice were better able to resolve Leishmania major infection and generated a superior T(H)1 immune response, as assessed from draining lymph nodes. In contrast, T(H)2-dependent allergic lung disease was markedly impaired in mutant mice. In both models, development of T(H)1 and T(H)2 cells in spleens was normal, but accumulation of T(H)2 (not T(H)1) cells at inflammatory sites was reduced. Thus, CD18 is selectively required for T(H)2, but not T(H)1, homing and has a minimal influence on T-effector development. These findings suggest a new integrin-based therapeutic approach in which the outcomes of diverse diseases may be favorably influenced by altering the homing of T(H)2 cells.

Abstract
A high-performance liquid chromatographic method for determination of amodiaquine (AQ), desethylamodiaquine (DAQ), chloroquine (CQ) and desethylchloroquine (DCQ) in human whole blood, plasma and urine is reported. 4-(4-Dimethylamino-1-methylbutylamino)-7-chloroquinoline was used as internal standard. The drugs and the internal standard were extracted into di-isopropyl ether as bases and then re-extracted into an acidic aqueous phase with 0.1 M phosphate buffer at pH 4.0 for AQ samples and at pH 2.5 for CQ filter paper samples. A C(18) column was used and the mobile phase consisted of methanol-phosphate buffer (0.1 M, pH 3)-perchloric acid (250: 747.5:2.5, v/v). The absorbance of the drugs was monitored at 333 nm and no endogenous compound interfered at this wavelength. The limit of quantification in whole blood, plasma and urine was 100 nM for AQ and DAQ (sample size 100 microliter) as well as for CQ and DCQ in blood samples dried on filter paper. For 1000 microliter AQ and DAQ samples, the limit of quantification was 10 nM in all three biological fluids. The within-assay and between-assay coefficients of variations were always <10% at the limits of quantification. Plasma should be preferred for the determination of AQ and DAQ since use of whole blood may be associated with stability problems.

Abstract
OBJECTIVES The objective of our qualitative study was to define modalities of psychological support to be offered to couples seeking medically assisted procreation. MATERIAL AND METHODS Forty couples participated in a semi-structured videotaped interview, which touched on themes such as personal and family histories, the couple's relationship, etc. We focused on the "narrative mobility", that is the way in which the couples transmit their personal and family history during the interview and the interviewer's impression that he may or may not share this with the couples. RESULTS Observed differences in narrative mobility led us to distinguish three groups of couples and to propose various types of psychological support. DISCUSSION AND CONCLUSION This exploratory study, with its interest for the narrative mobility, concerns the couples' capacity to stand back from their own story as responsible interlocutors. We made the hypothesis that this capacity is linked to their capacity to handle their emotional stress, to act as partners to the medical team and to prepare themselves for their future parenthood.

Abstract
BACKGROUND Intrapulmonary administration of IL-12 has been shown to inhibit the number of eosinophils in lung murine models of asthma, but the precise mechanism of this inhibition has not been reported. The purpose of this study was to examine whether IL-12 treatment inhibits bone marrow eosinophilopoiesis, and to elucidate the role of IFN-gamma in this process. OBJECTIVE To elucidate the in vivo and in vitro effects of IL-12 on eosinophil differentiation from murine bone marrow (BM) stem cells, and to examine the mechanistic role of IFN-gamma in this process. METHODS Allergen-sensitized BALB/c mice were administered low doses of intranasal IL-12 at the time of allergen challenge, and the number of eosinophils in BM was determined 3 days later. The direct actions of IL-12 on eosinophil differentiation from BM cells were determined in vitro. The mechanistic role of IFN-gamma was assessed by measuring IFN-gamma induction by IL-12 in BM cell cultures, and through the use of IFN-gamma KO mice. RESULTS Treatment of allergic mice with intrapulmonary IL-12 (1 ng or 10 ng) reduced eosinophils in BM by 43%. Culture of BM cells from allergen-sensitized mice with IL-3 + IL-5 induced eosinophil differentiation in vitro. Addition of IL-12 to these cultures inhibited eosinophil differentiation, with maximal inhibition (45%) occurring at 10 ng/mL IL-12 concentration. IL-12 induced IFN-gamma production from BM cultures, and failed to inhibit eosinophil differentiation in IFN-gamma-knockout mice, indicating a critical mechanistic role for IFN-gamma. CONCLUSION This study demonstrates that IL-12 selectively inhibits BM eosinophilopoiesis, and that this effect is mediated by IFN-gamma. Intrapulmonary IL-12 has suppressive effects on BM eosinophilopoiesis that may represent a novel mechanism contributing to the anti-eosinophilic effects of IL-12 in allergic airway disease.

Abstract
This study describes a nonisotopic polymerase chain reaction-reverse hybridization-based method (PCR-RH) for the one-step detection and genotyping of anogenital human papillomavirus (HPV) in a microwell format. HPV DNA was amplified and labeled by PCR using GP5+/GP6+ primers. Labeled amplicons were hybridized to 20 HPV type-specific capture probes anchored to the surface of plastic microwells and detected by an immunoenzymatic assay. Assay sensitivity was <50 pg labeled amplicon, and no cross-reactivity was observed, as determined by hybridizing serial dilutions of labeled PCR products to either matched or mismatched capture probes. The assay was tested on 66 clinical samples (23 specimens with normal histology, I fibropapilloma, 26 cervical intraepithelial neoplasia grade 1 [CIN1], 9 CIN2, and 7 CIN3) and compared with a method based on restriction fragment length polymorphism (RFLP) of PCR products. PCR-RH and PCR-RFLP performed equally well on clinical samples. The overall HPV detection rate was similar: 65.1% (43/66) for PCR-RH and 57.6% (38/66) for PCR-RFLP. HPV DNA was found in all CIN2 and CIN3 samples by both methods; however, PCR-RH detected more positives among normal biopsy samples and CINI cases. Overall, there was good agreement between the two genotyping methods, but RH yielded fewer cases with undetermined HPV genotype.

Abstract
We present the case of a 50-year old patient, operated on for three adjoining annular strictures in the jejunum with proximal dilatation. He presented with a one-year history of recurrent cramping in the upper abdomen and vomiting, with two episodes of intestinal obstruction. Microscopic examination of the stricture revealed, in the submucosa, disorganised fascicles of smooth muscle derived from the muscularis mucosae, bundles of non-myelinated nerve fibres with scattered abnormal ganglion cells and haemangiomatous vessels. The pathological findings observed were similar to those described as neuromuscular and vascular hamartoma, a rare stricturing condition of the small intestine. Many authors have questioned the hamartomatous nature of this disorder, since identical features may be seen in Crohn's disease, in ischaemic enteritis, in radiation enteritis and in non-steroidal antiinflammatory drug-induced small intestinal strictures. On the basis of a review of the 5 previously described cases and of our own experience, we believe that neuro muscular and vascular hamartoma of the small bowel should be considered as a distinct entity if histological hallmarks of Crohn's disease are absent, in patients with no history of gastrointestinal disease, or of chronic ingestion of non-steroidal antiinflammatory drugs.

Abstract
BACKGROUND We examined the value of deep sclerectomy combined with phacoemulsification as a surgical technique in the peri- and postoperative phases. MATERIALS AND METHODS Deep sclerectomy with phacoemulsification was carried out in 18 patients. Mean postoperative follow-up was 7.5 weeks. RESULTS Deep sclerectomy was more difficult to perform than goniotrephination. We observed neither fibrin reaction nor hypotonic dysregulation (intraocular pressure, IOP, < 8 mmHg). Five patients required additional pressure-lowering drugs during postoperative IOP regulation. CONCLUSION We consider the low inflammatory response in the early postoperative phase to outweigh the greater surgical difficulty and prolonged surgery time. Further studies must verify whether higher IOP during the early postoperative phase is sufficient for good long-term IOP regulation.

Abstract
INTRODUCTION Genotyping of Human papillomavirus (HPV) is an important step in the clinical evaluation of the oncogenic risk associated with HPV infection of cervical mucosa. The purpose of this work was to develop a fast PCR-reverse-hybridization assay (PCR-RH) for the simultaneous detection and genotyping of anogenital HPVs. METHODS HPV DNA from cervical biopsies was amplified by consensus primer-PCR. Digoxigenin-labeled PCR products were hybridized to type-specific probes anchored to the surface of plastic microwells and revealed by an ELISA system. RESULTS The method was tested on 115 clinical samples (81 koilocytic atypias, 11 CIN1, 10 CIN2, 12 CIN3 and 1 squamous carcinoma). HPV DNA was found in 56.7% koilocytic atypias, in 90.9% of CIN1 and in 100% of CIN2 and higher-grade lesions. Thus, PCR-RH is sensitive, rapid, easy-to-perform and readily applicable to the routine analysis of a large number of samples.

Abstract
INTRODUCTION Human Papillomavirus (HPV) infection is considered an important risk factor for the development of cervical carcinoma. The aim of this work was to detect and genotype HPV DNA in cervical lesions from our Province. METHODS HPV DNA was amplified by polymerase chain reaction (PCR) and genotyped by restriction fragment length polymorphism (RFLP) analysis. A total of 101 biopsies (43 koilocytic atypias, 20 CIN1, 19 CIN2, 17 CIN3 and 2 squamous carcinomas) were analyzed. RESULTS HPV DNA was found in 41.8% of koilocytic atypias, in 95.0% of CIN1 and 100% of CIN2 and higher grade lesions. Only high risk genotypes were found in CIN2-3 and invasive carcinomas. HPV 16 was the most prevalent type in both CIN1 and CIN2-3 and the only HPV type found in situ and invasive carcinomas. HPV type 51 was found in 21.0% of CIN1 but it was rare in CIN2 and absent in more advanced lesions.

Abstract
BACKGROUND We have previously found decreased CYP2C19 activity in Tanzanians tested with mephenytoin and omeprazole in relation to genotype when compared with white and Asian subjects. OBJECTIVE We investigated the impact of CYP2C19 genotype and phenotype on chloroguanide (INN, proguanil) metabolism to its metabolites cycloguanil and 4-chlorophenylbiguanide. METHODS A single oral chloroguanide dose was given to 25 healthy Tanzanian subjects with CYP2C19 genotypes (CYP2C19*1, CYP2C19*2, and CYP2C19*3). Homozygous wild-type and mutated genotype groups were chosen randomly, but the heterozygous genotype group was chosen with a range in phenotype. We used a novel HPLC method for drug determination. RESULTS Pharmacokinetics of chloroguanide did not differ between groups. Maximum plasma concentration (Cmax) and area under the plasma concentration versus time [AUC(0-infinity)] for cycloguanil was significantly lower (t test P < .05) in the homozygously mutated group compared with the homozygously wild-type group. There were similar significant group differences of median urinary excretion. The chloroguanide/cycloguanil ratio closely correlated (r(s) = .87) with omeprazole metabolic ratio, confirming that Tanzanian subjects are generally slower CYP2C19 metabolizers. It also confirms that CYP2C19 genotype and phenotype predicts cycloguanil formation. In addition, a 3-hour plasma sample metabolic ratio also seems to be a proper time for omeprazole phenotyping in Tanzanian subjects. Because the plasma concentrations of cycloguanil and 4-chlorophenylbiguanide covary (r(s) = .89), it is now suggested that their formation be catalyzed by the same enzyme (ie, CYP2C19) through a common intermediate, the structure of which is also presented. CONCLUSIONS As shown in an earlier study, also with a third substrate, Tanzanians have a lower capacity to form cycloguanil than white and Asian subjects. Individuals with two mutated alleles have lower metabolic capacity than individuals with two wild-type alleles or individuals in the heterozygous group, which may lead to chloroguanide therapeutic failure. This knowledge should be important when selecting appropriate patients and doses of chloroguanide in different populations.

Abstract
Olfactory neuroblastoma is an uncommon and hardly diagnosable neoplasm. The conventional histologic analysis allows generally a diagnosis of undifferentiated carcinoma. The immunohistochemical procedures, particularly the S-100 Protein and the Enolase Neuron-Specific, may contribute to define the diagnosis as well as in a patient recently observed by the authors.
