Abstract
OBJECTIVE Despite the high prevalence of epilepsy in Africa, evaluation of epilepsy research trends on the continent is lacking. Without establishing effective research, improvement in care for people with epilepsy cannot be effectively strategized or targeted. METHODS A scoping review of the peer-reviewed literature on epilepsy from Africa (1989-2019) was conducted. The aim was to understand from this what areas are well researched versus underresearched based on published epilepsy topics. RESULTS A total of 1227 publications were identified and assessed. A significant increase in publications occurred over the 30 years assessed. African author leadership was evident in most reports. Nine countries had >50 publications identified; the remaining 45 countries had <50 or no publications. Research studies were typically of lower quality (case series and observational studies). Research themes were more focused on clinical epilepsy (descriptive observational studies) and social aspects (qualitative surveys). However, there were a number of unique and strong themes, specifically for neurocysticercosis and nodding syndrome, where strong research collaborations were evident, basic science understandings were explored, and interventional models were established. SIGNIFICANCE Despite Africa being the continent with the most countries, it is lacking in the quantity, quality, and for some areas, relevance of research on epilepsy. Targeted approaches are needed to upskill the strength of research undertaken with more basic science, interventional, and randomized controlled studies. Themes of research need to promote those with unique African content but also to align with current international research areas that have impact on care delivery, such as epilepsy surgery and epilepsy genetics. For this to be possible, it is important to strengthen research hubs with collaborations that empower Africa to own its epilepsy research journey.

Abstract
Background Neurological COVID-19 disease has been reported widely, but published studies often lack information on neurological outcomes and prognostic risk factors. We aimed to describe the spectrum of neurological disease in hospitalised COVID-19 patients; characterise clinical outcomes; and investigate factors associated with a poor outcome. Methods We conducted an individual patient data (IPD) meta-analysis of hospitalised patients with neurological COVID-19 disease, using standard case definitions. We invited authors of studies from the first pandemic wave, plus clinicians in the Global COVID-Neuro Network with unpublished data, to contribute. We analysed features associated with poor outcome (moderate to severe disability or death, 3 to 6 on the modified Rankin Scale) using multivariable models. Results We included 83 studies (31 unpublished) providing IPD for 1979 patients with COVID-19 and acute new-onset neurological disease. Encephalopathy (978 [49%] patients) and cerebrovascular events (506 [26%]) were the most common diagnoses. Respiratory and systemic symptoms preceded neurological features in 93% of patients; one third developed neurological disease after hospital admission. A poor outcome was more common in patients with cerebrovascular events (76% [95% CI 67–82]), than encephalopathy (54% [42–65]). Intensive care use was high (38% [35–41]) overall, and also greater in the cerebrovascular patients. In the cerebrovascular, but not encephalopathic patients, risk factors for poor outcome included breathlessness on admission and elevated D-dimer. Overall, 30-day mortality was 30% [27–32]. The hazard of death was comparatively lower for patients in the WHO European region. Interpretation Neurological COVID-19 disease poses a considerable burden in terms of disease outcomes and use of hospital resources from prolonged intensive care and inpatient admission; preliminary data suggest these may differ according to WHO regions and country income levels. The different risk factors for encephalopathy and stroke suggest different disease mechanisms which may be amenable to intervention, especially in those who develop neurological symptoms after hospital admission.

Abstract
ObjectiveOur aim was to report neurological manifestations of children with paediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2 (PIMS-TS).MethodsPatients (<18yrs) presenting to Great Ormond Street Hospital between March 1, 2020, and June 21, 2020 fulfilling RCPCH PIMS-TS criteria, were included. Clinical and paraclinical features were retrieved retrospectively from electronic patient records.ResultsNew-onset neurological symptoms/signs were reported in 23/45 (51.1%); headaches (n=16), encephalopathy (n=7), dysarthria/dysphonia (n=6), hallucinations (n=4), ataxia (n=4), peripheral nerve involvement (n=3), and seizures (n=1). Five (21.7%) patients had CSF analysis; 1 patient had 118 leuko- cytes in CSF. Splenium signal changes were seen in 4/14 patients who had brain MRI. A mild excess of slow activity was found in 10/10 who had an EEG and mild myopathic and neuropathic changes were seen 4/5 who underwent nerve conduction studies and electromyography. Children with neurological involvement had higher peak inflammatory markers and were more likely to be ventilated and require inotropic support in PICU (p<0.05).ConclusionsChildren with PIMS-TS presented with new neurological symptoms involving both the central and peripheral nervous systems, in the absence of respiratory symptoms. Neurological symptoms were seen more frequently in more severe presentations.o.abdel-mannan@ucl.ac.uk

Abstract
OBJECTIVE To characterize a cohort of children with epilepsia partialis continua (EPC) and develop a diagnostic algorithm incorporating key differential diagnoses. METHODS Children presenting with EPC to a tertiary pediatric neurology center between 2002 and 2019 were characterized. RESULTS Fifty-four children fulfilled EPC criteria. Median age at onset was 7 years (range 0.6-15), with median follow-up of 4.3 years (range 0.2-16). The diagnosis was Rasmussen encephalitis (RE) in 30 of 54 (56%), a mitochondrial disorder in 12 of 54 (22.2%), and magnetic resonance imaging (MRI) lesion-positive focal epilepsy in 6 of 54 (11.1%). No diagnosis was made in 5 of 54 (9%). Children with mitochondrial disorders developed EPC earlier; each additional year at presentation reduced the odds of a mitochondrial diagnosis by 26% (P = .02). Preceding developmental concerns (odds ratio [OR] 22, P < .001), no seizures prior to EPC (OR 22, P < .001), bilateral slowing on electroencephalogram (EEG) (OR 26, P < .001), and increased cerebrospinal fluid (CSF) protein level (OR 16) predicted a mitochondrial disorder. Asymmetry or hemiatrophy was evident on MRI at presentation with EPC in 18 of 30 (60%) children with RE, and in the remainder at a median of 6 months (range 3-15) after EPC onset. The first diagnostic test is brain MRI. Hemiatrophy may permit a diagnosis of RE with unilateral clinical and EEG findings. For children in whom a diagnosis of RE cannot be made on first scan but the clinical and radiological presentation resembles RE, repeat imaging every 6 months is recommended to detect progressive unicortical hemiatrophy, and brain biopsy should be considered. Evidence of intrathecal inflammation (oligoclonal bands and raised neopterin) can be supportive. In children with bihemispheric EPC, rapid polymerase gamma testing is recommended and if negative, sequencing mtDNA and whole-exome sequencing on blood-derived DNA should be performed. SIGNIFICANCE Children presenting with EPC due to a mitochondrial disorder show clinical features distinguishing them from RE and structural epilepsies. A diagnostic algorithm for children with EPC will allow targeted investigation and timely diagnosis.

Abstract
OBJECTIVE The authors' aim was to characterize a single-center experience of brain biopsy in pediatric cryptogenic neurological disease. METHODS The authors performed a retrospective review of consecutive brain biopsies at a tertiary pediatric neurosciences unit between 1997 and 2017. Children < 18 years undergoing biopsy for neurological pathology were included. Those with presumed neoplasms and biopsy performed in the context of epilepsy surgery were excluded. RESULTS Forty-nine biopsies in 47 patients (25 females, mean age ± SD 9.0 ± 5.3 years) were performed during the study period. The most common presenting symptoms were focal neurological deficit (28.6%) and focal seizure (26.5%). Histopathological, microbiological, and genetic analyses of biopsy material were contributory to the diagnosis in 34 cases (69.4%). Children presenting with focal seizures or with diffuse (> 3 lesions) brain involvement on MRI were more likely to yield a diagnosis at biopsy (OR 3.07 and 2.4, respectively). Twelve patients were immunocompromised and were more likely to yield a diagnosis at biopsy (OR 6.7). Surgery was accompanied by severe complications in 1 patient. The most common final diagnoses were infective (16/49, 32.7%), followed by chronic inflammatory processes (10/49, 20.4%) and occult neoplastic disease (9/49, 18.4%). In 38 cases (77.6%), biopsy was considered to have altered clinical management. CONCLUSIONS Brain biopsy for cryptogenic neurological disease in children was contributory to the diagnosis in 69.4% of cases and changed clinical management in 77.6%. Biopsy most commonly revealed underlying infective processes, chronic inflammatory changes, or occult neoplastic disease. Although generally safe, the risk of severe complications may be higher in immunocompromised and myelosuppressed children.

Abstract
Introduction: The growing impact of non-communicable diseases in low- to middle-income countries makes epilepsy a key research priority. We evaluated peer-reviewed published literature on childhood epilepsy specific to Kenya to identify knowledge gaps and inform future priorities. Methodology: A literature search utilizing the terms “epilepsy” OR “seizure” as exploded subject headings AND “Kenya” was conducted. Relevant databases were searched, generating 908 articles. After initial screening to remove duplications, irrelevant articles, and publications older than 15 years, 154 papers remained for full-article review, which identified 35 publications containing relevant information. Data were extracted from these reports on epidemiology, etiology, clinical features, management, and outcomes. Results: The estimated prevalence of lifetime epilepsy in children was 21–41 per 1,000, while the incidence of active convulsive epilepsy was 39–187 cases per 100,000 children per year. The incidence of acute seizures was 312–879 per 100,000 children per year and neonatal seizures 3,950 per 100,000 live births per year. Common risk factors for both epilepsy and acute seizures included adverse perinatal events, meningitis, malaria, febrile seizures, and family history of epilepsy. Electroencephalography abnormalities were documented in 20%–41% and neurocognitive comorbidities in more than half. Mortality in children admitted with acute seizures was 3%–6%, and neurological sequelae were identified in 31% following convulsive status epilepticus. Only 7%–29% children with epilepsy were on antiseizure medication. Conclusion: Active convulsive epilepsy is a common condition among Kenyan children, remains largely untreated, and leads to extremely poor outcomes. The high proportion of epilepsy attributable to preventable causes, in particular neonatal morbidity, contributes significantly to the lifetime burden of the condition. This review reaffirms the ongoing need for better public awareness of epilepsy as a treatable disease and for national-level action that targets both prevention and management.

Abstract
In a range of animal species, exposure of the brain to general anaesthesia without surgery during early infancy may adversely affect its neural and cognitive development. The mechanisms mediating this are complex but include an increase in brain cell death. In humans, attempts to link adverse cognitive development to infantile anaesthesia exposure have yielded ambiguous results. One caveat that may influence the interpretation of human studies is that infants are not exposed to general anaesthesia without surgery, raising the possibility that surgery itself, may contribute to adverse cognitive development. Using piglets, we investigated whether a minor surgical procedure increases cell death and disrupts neuro-developmental and cognitively salient gene transcription in the neonatal brain. We randomly assigned neonatal male piglets to a group who received 6h of 2% isoflurane anaesthesia or a group who received an identical anaesthesia plus 15 mins of surgery designed to replicate an inguinal hernia repair. Compared to anesthesia alone, surgery-induced significant increases in cell death in eight areas of the brain. Using RNAseq data derived from all 12 piglets per group we also identified significant changes in the expression of 181 gene transcripts induced by surgery in the cingulate cortex, pathway analysis of these changes suggests that surgery influences the thrombin, aldosterone, axonal guidance, B cell, ERK-5, eNOS and GABAA signalling pathways. This suggests a number of novel mechanisms by which surgery may influence neural and cognitive development independently or synergistically with the effects of anaesthesia.

Abstract
Exposure of the brain to general anesthesia during early infancy may adversely affect its neural and cognitive development. The mechanisms mediating this are complex, incompletely understood and may be sexually dimorphic, but include developmentally inappropriate apoptosis, inflammation and a disruption to cognitively salient gene expression. We investigated the effects of a 6h isoflurane exposure on cell death, microglial activation and gene expression in the male neonatal piglet brain. Piglets (n = 6) were randomised to: (i) naive controls or (ii) 6h isoflurane. Cell death (TUNEL and caspase-3) and microglial activation were recorded in 7 brain regions. Changes in gene expression (microarray and qPCR) were assessed in the cingulate cortex. Electroencephalography (EEG) was recorded throughout. Isoflurane anesthesia induced significant increases in cell death in the cingulate and insular cortices, caudate nucleus, thalamus, putamen, internal capsule, periventricular white matter and hippocampus. Dying cells included both neurons and oligodendrocytes. Significantly, microglial activation was observed in the insula, pyriform, hippocampus, internal capsule, caudate and thalamus. Isoflurane induced significant disruption to the expression of 79 gene transcripts, of these 26 are important for the control of transcription and 23 are important for the mediation of neural plasticity, memory formation and recall. Our observations confirm that isoflurane increases apoptosis and inflammatory responses in the neonatal piglet brain but also suggests novel additional mechanisms by which isoflurane may induce adverse neural and cognitive development by disrupting the expression of genes mediating activity dependent development of neural circuits, the predictive adaptive responses of the brain, memory formation and recall.

Abstract
Cooling to 33.5 °C in babies with neonatal encephalopathy significantly reduces death and disability, however additional therapies are needed to maximize brain protection. Following hypoxia–ischemia we assessed whether inhaled 45–50% Argon from 2–26 h augmented hypothermia neuroprotection in a neonatal piglet model, using MRS and aEEG, which predict outcome in babies with neonatal encephalopathy, and immunohistochemistry. Following cerebral hypoxia–ischemia, 20 Newborn male Large White piglets < 40 h were randomized to: (i) Cooling (33 °C) from 2–26 h (n = 10); or (ii) Cooling and inhaled 45–50% Argon (Cooling + Argon) from 2–26 h (n = 8). Whole-brain phosphorus-31 and regional proton MRS were acquired at baseline, 24 and 48 h after hypoxia–ischemia. EEG was monitored. At 48 h after hypoxia–ischemia, cell death (TUNEL) was evaluated over 7 brain regions. There were no differences in body weight, duration of hypoxia–ischemia or insult severity; throughout the study there were no differences in heart rate, arterial blood pressure, blood biochemistry and inotrope support. Two piglets in the Cooling + Argon group were excluded. Comparing Cooling + Argon with Cooling there was preservation of whole-brain MRS ATP and PCr/Pi at 48 h after hypoxia–ischemia (p < 0.001 for both) and lower 1H MRS lactate/N acetyl aspartate in white (p = 0.03 and 0.04) but not gray matter at 24 and 48 h. EEG background recovery was faster (p < 0.01) with Cooling + Argon. An overall difference between average cell-death of Cooling versus Cooling + Argon was observed (p < 0.01); estimated cells per mm2 were 23.9 points lower (95% C.I. 7.3–40.5) for the Cooling + Argon versus Cooling. Inhaled 45–50% Argon from 2–26 h augmented hypothermic protection at 48 h after hypoxia–ischemia shown by improved brain energy metabolism on MRS, faster EEG recovery and reduced cell death on TUNEL. Argon may provide a cheap and practical therapy to augment cooling for neonatal encephalopathy. 45–50% Argon augments brain protection above hypothermia after neonatal hypoxia–ischemia. No physiological or biochemical change occurred with the 24 h exposure of 45–50% Argon. 45–50% Argon led to faster recovery of aEEG, and improved cerebral metabolism on MRS. TUNEL + cells were ~ 24 points lower per mm2 with Argon augmented cooling v cooling. Argon was practical to administer with a standard neonatal ventilator (unlike xenon).

Abstract
BACKGROUND AND PURPOSE In infants with moderate to severe neonatal encephalopathy, whole-body cooling at 33°C to 34°C for 72 hours is standard care with a number needed to treat to prevent a adverse outcome of 6 to 7. The precise brain temperature providing optimal neuroprotection is unknown. METHODS After a quantified global cerebral hypoxic-ischemic insult, 28 piglets aged <24 hours were randomized (each group, n=7) to (1) normothermia (38.5°C throughout) or whole-body cooling 2 to 26 hours after insult to (2) 35°C, (3) 33.5°C, or (4) 30°C. At 48 hours after hypoxia-ischemia, delayed cell death (terminal deoxynucleotidyl transferase deoxyuridine triphosphate nick end labeling and cleaved caspase 3) and microglial ramification (ionized calcium-binding adapter molecule 1) were evaluated. RESULTS At 48 hours after hypoxia-ischemia, substantial cerebral injury was found in the normothermia and 30°C hypothermia groups. However, with 35°C and 33.5°C cooling, a clear reduction in delayed cell death and microglial activation was observed in most brain regions (P<0.05), with no differences between 35°C and 33.5°C cooling groups. A protective pattern was observed, with U-shaped temperature dependence in delayed cell death in periventricular white matter, caudate nucleus, putamen, hippocampus, and thalamus. A microglial activation pattern was also seen, with inverted U-shaped temperature dependence in periventricular white matter, caudate nucleus, internal capsule, and hippocampus (all P<0.05). CONCLUSIONS Cooling to 35°C (an absolute drop of 3.5°C as in therapeutic hypothermia protocols) or to 33.5°C provided protection in most brain regions after a cerebral hypoxic-ischemic insult in the newborn piglet. Although the relatively wide therapeutic range of a 3.5°C to 5°C drop in temperature reassured, overcooling (an 8.5°C drop) was clearly detrimental in some brain regions.

Abstract
The relationship between cerebral autoregulation (CA) and the neurotoxic effects of anaesthesia with and without surgery is investigated. Newborn piglets were randomly assigned to receive either 6 h of anaesthesia (isoflurane) or the same with an additional hour of minor surgery. The effect of the spontaneous changes in mean arterial blood pressure (MABP) on the cerebral haemodynamics (oxy- and deoxy-haemoglobin, HbO2 and Hb) was measured using transverse broadband near-infrared spectroscopy (NIRS). A marker for impaired CA, concordance between MABP and intravascular oxygenation (HbD = HbO2 - Hb) in the ultra-low frequency domain (0.0018-0.0083 Hz), was assessed using coherence analysis. Presence of CA impairment was not significant but found to increase with surgical exacerbation. The impairment did not correlate with histological outcome (presence of cell death, apoptosis and microglial activation in the brain).

Abstract
Accumulating preclinical and clinical evidence suggests the possibility of neurotoxicity from neonatal exposure to general anaesthetics. Here, we review the weight of the evidence from both human and animal studies and discuss the putative mechanisms of injury and options for protective strategies. Our review identified 55 rodent studies, seven primate studies, and nine clinical studies of interest. While the preclinical data consistently demonstrate robust apoptosis in the nervous system after anaesthetic exposure, only a few studies have performed cognitive follow-up. Nonetheless, the emerging evidence that the primate brain is vulnerable to anaesthetic-induced apoptosis is of concern. The impact of surgery on anaesthetic-induced brain injury has not been adequately addressed yet. The clinical data, comprising largely retrospective cohort database analyses, are inconclusive, in part due to confounding variables inherent in these observational epidemiological approaches. This places even greater emphasis on prospective approaches to this problem, such as the ongoing GAS trial and PANDA study.

Abstract
Proteoglycan distribution during corneal stromal healing in growing corneas of young chicks were histologically and immunohistochemically analysed. Single linear incisions to produce partial-thickness wounds were made in the corneas of 5 day old chicks. The corneas were harvested at different times after wounding and processed for either histochemical analyses using periodic acid-Schiff's reaction (PAS) or for indirect immunofluorescence analyses of lumican, keratocan, keratan sulfate, perlecan and laminin. Linear corneal stromal incisions were completely covered by migrated stratified epithelium by day 2 post wounding and resulted in a gaping wound with a thinner stroma. New stromal scar tissue formed between the epithelium and the original stroma that resulted in partial restoration of stromal thickness. During the first two to three weeks of healing, the stromal tissue filling the depression formed from the gaping wound, was hypercellular and PAS positive, indicating significantly higher levels of glycoprotein content but no new Bowman's membrane was formed. By four weeks, the scar tissue occupied a 2-3 mm wide region. Immunofluorescence analyses indicated that other major differences in the healing and normally growing stroma were the increased synthesis and deposition of perlecan and laminin. No differences were evident in the immunofluorescence for keratocan or keratan sulfate in the scar tissue, but the scar tissue did contain markedly decreased levels of lumican. Thus, the regulation of proteoglycan and glycoprotein synthesis is altered in the keratocytes that are recruited to the wounded regions in the growing corneal stroma of post-hatched young chicks. While synthesis and deposition of adhesive molecules including laminin and perlecan are elevated, the synthesis of one of the keratan sulfate proteoglycans, lumican, is reduced in the scar tissue as compared to the normally growing stroma.

Abstract
PURPOSE The authors have developed monoclonal antibodies (mAbs) to characterize the sequential biochemical changes in corneal epithelial cells after they differentiate from stem cells, located in the limbus, and migrate centripetally to follow the pathway of terminal differentiation. The purpose of this study was to identify a protein (recognized by mAb HE1/11F) with increased expression associated with the transition of the limbal epithelium to corneal epithelium. METHODS The distribution and identification of the protein(s) were performed using an indirect immunohistochemical staining technique and a western blot analysis, respectively. A rabbit corneal epithelial cDNA library, constructed in the Uni-Zap XR vector, was screened with mAb HE1/11F to select cDNA clones expressing polypeptide(s) recognized by this mAb. Additional overlapping cDNA clones were obtained from a primer extension cDNA library to determine the sequence of the complete open reading frame encoding the protein recognized by mAb HE1/11F. RESULTS Rabbit corneal epithelium exhibited strong immunostaining with mAb HE1/11F, however, the limbal epithelial cells stained weakly. HE1/11F recognized 160-kDa (HEBM1) and 100-kDa (HEBM2) polypeptides in the corneal epithelial extracts. The amino acid sequence of the protein deduced from the nucleotide sequence of the cDNA exhibited a close homology to that of a RhoA (Ras-related small GTPase)-associated serine-threonine kinase (ROCK-I or Rho-associated coiled-coil kinase). A 160-kDa RhoA-binding polypeptide with a molecular mass similar to that of HEBM1 and ROCK-I was detected in the corneal epithelial extracts. These findings strongly suggested that HEBM1 was rabbit ROCK-I. The identity of HEBM1 was further confirmed from the reactivity of mAb HE1/11F with ROCK-I immunoprecipitated from rabbit corneal epithelial extracts using anti-ROCK-I antibodies. CONCLUSIONS The increased expression of a protein identified as ROCK-I from cDNA analyses is associated with rabbit corneal epithelial differentiation and transition from the limbal to corneal surface. Therefore, a RhoA signaling pathway is likely to be associated with corneal epithelial differentiation (maturation). A close homology among the cDNA sequences of rabbit, mouse, rat, and human ROCK-I indicates that this RhoA-associated kinase is a well-conserved protein.

Abstract
Perlecan and aggrecan are proteoglycans that receive primarily heparan sulfate and chondroitin sulfate side chains, respectively. Their large multidomained core proteins have little or no homology to each other and their glycosaminoglycan (GAG) attachment sites are restricted to certain domains only. We examined the involvement of the non-GAG bearing domains in designating the GAG type added to the GAG attachment domain by preparing cDNA constructs that expressed perlecan/aggrecan chimeras as recombinant products in COS-7 cells and then determining the size and GAG composition of the recombinant products. The results showed that domain I of perlecan receives primarily (73-81%) heparan sulfate when coupled with domain II and III of perlecan, but when coupled with the G3 domain of aggrecan, it receives primarily (59-63%) chondroitin sulfate. Furthermore, the chondroitin sulfate attachment region of aggrecan received GAG side chains more readily when coupled to the G3 domain of aggrecan than when coupled to domains II and III of perlecan. The GAG side chains on all these recombinant products were small and similar in size. These findings indicate that the utilization of attachment sites for heparan and chondroitin sulfate or the sulfation of these GAGs can be influenced, in part, by non-GAG bearing domains.

Abstract
Segmentation of the peripheral nervous system of vertebrates requires guidance cues located in the adjacent somitic mesoderm. Recent experiments suggest that inhibitory molecules in the posterior somite may influence segmentation by restricting the outgrowth of axons and the migration of neural crest cells to the anterior somite. A potential candidate for an inhibitory molecule is collagen IX, a chondroitin sulfate proteoglycan made by sclerotome cells of the somite and by the notochord. Immunohistochemical localization of collagen IX demonstrated that its expression in the posterior sclerotome of the somite correlates with axon outgrowth and neural crest cell migration through the anterior sclerotome. In vitro, sensory neurites on fibronectin, and motor neurites on basal lamina extract, avoid regions which contain substrate-bound collagen IX. This effect can be abolished by chondroitinase treatment, suggesting that the glycosaminoglycan component of the molecule is responsible for this activity. Further, collagen IX elicits a similar avoidance behavior by neural crest cells in vitro. These data suggest that collagen IX contributes to the segmentation of the peripheral nervous system in vivo.

Abstract
Cartilage has unique physical characteristics attributable to the presence of an unusually high content of proteoglycan embedded in the network of collagen fibrils. Advances in understanding the structure of these components and how their synthesis is regulated have been greatly assisted by the application of molecular biology. For example, an immortalized rat chondrocyte cell line was obtained by infection with a recombinant retrovirus encoding the myc gene product. Several positive and negative DNA regulatory elements of the collagen II gene have been identified that appear to be important in the regulation of this gene in chondrocytes. The complete primary structure of the cartilage proteoglycan (aggrecan) core protein deduced from cDNA sequence displays a complex multidomain structure including numerous repeats of Ser-Gly sequences and sequence homologies with link protein and animal lectins. Such studies advance our understanding of normal morphogenetic events and lay the groundwork for determining the basis of molecular and genetic defects.

Abstract
Microinjection of the firefly luciferase gene coupled to a thymidine kinase (tk) promoter provided a quantitative assay to evaluate the requirements for gene expression in individual mouse oocytes and embryos. Polyoma virus (PyV) enhancers had no effect on the level of gene expression or competition for transcription factors as long as the DNA remained either in the oocyte germinal vesicle or the pronuclei of one-cell embryos. Expression of injected genes could be observed in pronuclei because the signal that normally triggers zygotic gene expression in two-cell embryos still occurred in one-cell embryos arrested in S phase. However, when the tk promoter was injected into zygotic nuclei of two-cell embryos, enhancers increased the number of embryos that expressed luciferase as well as the level of luciferase activity per embryo. PyV enhancer mutation F101, selected for growth in mouse embryonal carcinoma F9 cells, stimulated expression in developing two-cell embryos about seven times better than the wild-type PyV enhancer and competed effectively for factors required for transcription. These results were consistent with the fact that enhancers are required to activate the PyV origin of DNA replication in developing two-cell embryos but not in one-cell embryos. The maximum levels of gene expression in oocytes, one-cell embryos, and developing two-cell embryos (1:67:21) were inversely related to the extent of chromatin assembly, but the need for enhancers was independent of chromatin assembly. Therefore, it appears that the need for enhancers to activate promoters or origins of replication results from some negative regulatory factor that first appears as a component of zygotic nuclear structure.

Abstract
Two immunocytochemical probes were used to specifically identify and localize heparan sulphate proteoglycans (HSPGs) in 17 cases of Alzheimer's disease (AD). A monoclonal (HK-102) and an affinity-purified polyclonal antibody, each recognizing specific domains on the protein core of a basement membrane-derived HSPG, localized HSPGs to the amyloid fibrils present in neuritic plaques (NPs) and congophilic angiopathy (CA) in the brains of Alzheimer's patients, with weak to no immunostaining in neurofibrillary tangles from the same tissues. HSPGs were also demonstrated in "primitive plaques," suggesting that their accumulation takes place during early stages of plaque development. Immunolocalization of HSPGs to subsets of astrocytes and neuronal cells, particularly those in close proximity to NPs and CA, suggested possible involvement of these two cell types in deposition of HS-PGs into the amyloidotic lesions. The current study not only identifies a new component (HSPGs) present in the amyloid deposits of NPs and CA but also suggests that astrocytes, neurons, or both may be involved in its deposition at these sites.

Abstract
When primary mouse mammary epithelial cells are cultured on plastic, they rapidly lose their ability to synthesize and secrete most milk proteins even in the presence of lactogenic hormones, whereas cells cultured on released type I collagen gels show greatly enhanced mRNA levels and secretion rates of beta-casein and of some other milk proteins. We show here that culture on a reconstituted basement membrane from Engelbreth-Holm-Swarm tumor (EHS) allows greater than 90% of cells to produce high levels of beta-casein. By comparison, 30-40% of cells on released type 1 gels and only 2-10% of cells on plastic express beta-casein after 6 days in culture. Because only 40% of cells from late pregnant gland produced beta-casein before culture, the EHS matrix can both induce and maintain an increased level of casein gene expression. Individual basal lamina components were also evaluated. Type IV collagen and fibronectin had little effect on morphology and beta-casein mRNA levels. In contrast, both laminin and heparan sulfate proteoglycan increased beta-casein mRNA levels (1.5- to 4-fold and 2- to 8-fold, respectively). However, for heparan sulfate proteoglycan, increased message was not accompanied by increased secretion of beta-casein. Profound morphological differences were evident between cells cultured on plastic and on EHS matrix, the latter cells forming ducts, ductules, and lumina and resembling secretory alveoli. These results emphasize the vital role of the extracellular matrix in receiving and integrating structural and functional signals that can direct specific gene expression in differentiated tissues.

Abstract
Confluent cultures of rat glomerular epithelial and mesangial cells were studied by immunofluorescent microscopy, using affinity-purified antibodies directed against collagen of type I-V or an antiserum directed against a basement membrane (BM) proteoglycan. The epithelial cells were stained by antibodies directed against type I, IV and V collagen, whereas the mesangial cells were stained by all the antibodies directed against the different collagenous antigens tested. Therefore, only mesangial cells contained antigenic determinants of type III collagen. On the contrary, both cell types possessed BM proteoglycan antigens. The data suggest that rat glomerular epithelial and mesangial cells may be implicated in the biosynthesis of different components of normal (and pathological) glomerular BM.

Abstract
The relationship between nurse counseling of hysterectomy patients and sexual adjustment following surgery was the focus of this descriptive study. Of 108 premenopausal women admitted to seven hospitals in California, New Mexico, and Utah who completed a series of questionnaires preoperatively, postoperatively, and eight weeks post-surgery, only 11 percent identified the nurse as the person who supplied the most valuable information. Self-reported sexual adjustment following surgery was significantly (p=.001) related to their presurgical pattern. Almost half the respondents wrote comments urging nurses to initiate discussion about the effect of hysterectomy on sexuality.

Abstract
Patients with diabetes receiving instruction in group classes utilizing audiovisual teaching techniques achieved significantly higher post-test scores than those taught individually in the traditional bedside manner. In addition to the significantly greater learning, the dietitian's time was reduced by 100 per cent, based on classes of eight patients. The study was conducted by randomly allocating forty-five qualified patients to control or experimental groups, pre-testing them using a questionaire-interview, giving bedside or class dietary instruction, and post-testing, using the same questionaire. Various personal characteristcs of the participants, as well as data relating to the diabetic state, were also examined for possible relationships to test scores and to one another.

Abstract
Twenty-four female homosexuals and 24 female heterosexuals matched for age and education were given the Draw-A-Person Test (DAP) and, on the Gough-Heilbrun Adjective Check List (ACL), were asked to describe themselves, men in general, and women in general. Results indicated that homosexuals, relative to the heterosuxual controls: (a) sexualized their drawings (p smaller than .02) and embellished the female figure more (p smaller than .05); (b) showed no evidence of confusion in gender identity on the DAP or ACL; (c) scored sifnigicantly higher on Autonomy, Change, and Exhibition on the ACL; and (d) scored significantly lower on Abasement, Defensiveness, Deference, Endurance, Order, Personal Adjustment and Self-control on the ACL. It was concluded that the female homosexual may be more independent, changeable, and sexually preoccupied and less well adjusted than her heterosexual counterpart.

Abstract
Diimidoesters are bifunctional reagents which react with the ε-amino group of lysine, forming intermolecular cross-links with minimal alteration of the native properties of proteins. To determine the optimal conditions for tissue fixation with diimidoesters, a cross-linking assay was developed based on the assumption that protein aggregates formed by intermolecular cross-links would be water-insoluble. With this assay method, the proportion of insoluble protein in fresh liver was 16%, while optimal conditions for cross-linking with the diimidoester, dimethylsuberimidate (DMS) (16-20 mg/ml, 0.02 M Ca++ and 0.15 M Tris-HCl, pH 9.5), rendered 92.1% insoluble and permitted only 3.3% of the protein to diffuse into the fixative solution. The smaller diimidoesters, dimethyladipimate and dimethylmalonimidate, rendered 74 and 16% of the protein insoluble, respectively. Fixation with various aldehydes produced insoluble fractions varying from 74% to over 90%. Ultrastructurally, hepatocytes of DMS-fixed liver and glutaraldehyde-fixed liver were similar except that with the former fixative the Golgi saccules and smooth endoplasmic reticulum were dilated and mitochondrial matrices exhibited an increased electron density. Furthermore, the appearance of glutaraldehyde- and DMS-fixed liver was more readily correlated with the degree of cross-linking than with the pH of the fixative solution per se. The results of this study indicate that DMS is a potentially useful fixative for light and electron microscopy.
