Neonates presenting with seizures are frequently assessed and managed by neonatologists in the NICU. Although hypoxic-ischemic encephalopathy and infection are common underlying causes of neonatal seizures, many patients with neonatal epilepsy will have an identifiable genetic etiology. Often these cases will be evaluated in collaboration with a geneticist. The categories of genetic causes of neonatal seizures include 1) structural brain malformations; 2) inborn errors of metabolism; 3) syndromic; and 4) nonsyndromic, single gene. Evaluation of these patients involves a comprehensive history and examination, followed by appropriate investigations and diagnostic genetic testing. Components of the diagnostic process will vary based on the clinical suspicion and differential diagnoses. In certain cases, syndromic surveillance for evaluation of other congenital anomalies may be recommended. Determination of the underlying genetic diagnosis, when present, will have important implications for treatment. Targeted therapies are currently available for specific genetic syndromes, and outcomes may improve with earlier initiation of therapy. Certain genetic diagnoses may also have guideline-based management involving screening for other manifestations of the disorder.Metabolic disorders in a neonate can present with involvement of any organ system and can be challenging to diagnose. A newborn can present with an acute metabolic crisis such as hyperammonemia or seizures needing immediate management, with a more chronic clinical picture such as cholestatic liver disease, or with structural abnormalities such as skeletal manifestations. Early detection of treatable metabolic conditions is important to improve outcomes. Newborn screening has facilitated early detection and initiation of therapy for many metabolic disorders. However, normal testing does not rule out a metabolic disorder and a high index of suspicion should remain when caring for any critically ill neonate without a diagnosis. Whole exome sequencing (WES) or whole genome sequencing (WGS) can be powerful tools in rapid diagnosis of a potentially treatable metabolic condition in a critically ill neonate. This review presents classic clinical presentations of neonatal metabolic disorders and also highlights some uncommon neonatal manifestations of metabolic disorders to improve the recognition and diagnosis of these conditions.Genetic targeting of specific cell types is fundamentally important for modern molecular-genetic studies. The development of simple methods to engineer high-capacity vectors-in particular, bacterial artificial chromosomes (BACs)-for the preparation of transgenic lines that accurately express a gene of interest has resulted in commonplace usage of transgenic techniques in a wide variety of experimental systems. Here we provide a brief description of each of the four major types of large-capacity vectors, with a focus on the use of BAC vectors.For most immunochemical methods, tissue culture supernatants will be the most useful source of monoclonal antibodies. The supernatants are not contaminated with high levels of other antibodies, and the concentration is high enough for most assays if used undiluted. This protocol describes the procedure of collecting tissue culture supernatants. When collecting supernatants for antibodies, allow the individual cultures to grow until the hybridomas die. This will allow collection of higher-titer supernatants. In general, antibodies are resistant to the proteases that are released from dying cells, so allowing the cells to die should not affect the quality of the antibodies. If extraneous IgG molecules will alter any of the assays for which the supernatants are being prepared, use medium with fetal bovine serum or use serum-free medium. The yield of this method is ∼20-50 µg of antibody/mL of supernatant. The most common problem encountered in storage of tissue culture supernatants after collection is contamination with bacteria or fungi. This can be prevented by the addition of sodium azide as described.Hybridoma and myeloma cell lines can be stored by slowly freezing cells in an appropriate solution of nutrients and a cryoprotectant such as glycerol or dimethyl sulfoxide (DMSO). A-438079 in vivo In this protocol, cells are centrifuged at 4°C, resuspended in cold freezing solution (10% DMSO in FBS), and then transferred to an appropriate freezing vial. The vials are slowly frozen to -70°C in Styrofoam racks and then stored in liquid nitrogen (LN2). Cells stored in LN2 will remain viable for years. Once a frozen vial has been removed from LN2 storage, it should be thawed as described, grown out into log phase, and refrozen.This protocol describes methods for isolation of total DNA from a strain of Sacchromyces cerevisiae carrying a recombinant yeast artificial chromosome (YAC). This method is appropriate for preparing DNA that will be subjected to regular agarose gel electrophoresis, Southern blotting, subcloning, genomic library construction, polymerase chain reaction (PCR), or other methods that do not require intact high-molecular-weight DNA. Because the linear YAC DNAs are sensitive to shearing forces, pipettes with wide-bore tips should be used to transfer DNAs. Drop dialysis should be used to exchange buffers. The expected yield from a 10-mL culture is 2-4 µg of yeast DNA.
Thiopurines are widely used as maintenance therapy in inflammatory bowel disease (IBD) but the evidence base for their use is sparse and their role increasingly questioned. Using the largest series reported to date, we assessed the long-term effectiveness of thiopurines in ulcerative colitis (UC) and Crohn's disease (CD), including their impact on need for surgery.

Outcomes were assessed in 11 928 patients (4968 UC, 6960 CD) in the UK IBD BioResource initiated on thiopurine monotherapy with the intention of maintaining medically induced remission. Effectiveness was assessed retrospectively using patient-level data and a definition that required avoidance of escalation to biological therapy or surgery while on thiopurines. Analyses included overall effectiveness, time-to-event analysis for treatment escalation and comparison of surgery rates in patients tolerant or intolerant of thiopurines.

Using 68 132 patient-years of exposure, thiopurine monotherapy appeared effective for the duration of treatment in 2617/4968 (52.
