Mechanisms of cell cycle remodeling at the MBT during the development of Xenopus laevis embryos
… checkpoints. At the midblastula transition (MBT), the cell cycle is remodeled as the division time lengthens and checkpoints are acquired. Initiation of the MBT depends upon the degradation of maternally supplied cyclin E, which is the regulatory partner of the cyclin dependent kinase, Cdk2. …

Molekulare und funktionelle Analyse der p21-aktivierten Kinase Mbt (mushroom bodies tiny) in der Augen- und Pilzkörperentwicklung von Drosophila melanogaster
Diese Arbeit beschäftigt sich mit Mbt, einem hochkonservierten Signalmolekül aus der Familie der p21-aktivierten Kinasen (PAK) aus Drosophila, während der Augen- und Pilzkörperentwicklung. Mbt wird aufgrund von Sequenzhomologien der PAK Unterfamilie II (PAK4-6) zugeordnet. PAK4-6 binden …

A standard European tank? Procurement politics, technology transfer and the challenges of collaborative MBT projects in the NATO alliance since 1945
… collaborative international main battle tank (MBT) projects since 1945. This thesis seeks to answer this question by considering four case studies of failed attempts to produce an MBT through an international collaborative tank project: first and second, the Franco-German efforts to produce a …

Loss of Chk1 Function and Exogenous Expression of Cyclin A1/Cdk2 Results in Apoptosis after the MBT in Early Xenopus laevis Embryos
… a period called the midblastula transition (MBT). At the MBT, the embryo undergoes a period of developmental remodeling: gap phases are acquired, zygotic transcription is initiated, and the maternal mRNAs are degraded. After the MBT, checkpoint pathways can be activated in response to …

Experiencing health services and mentalisation-based treatment for borderline personality disorder : service user perspectives
… the experience of mentalisation-based treatment (MBT) for BPD from the perspective of adult service users. Seven participants were interviewed and findings illustrate that the group component of MBT was experienced as challenging and unpredictable. Trust was identified as key to benefitting from …

The Role of Chk2 and Wee1 Protein Kinases during the Early Embryonic Development of Xenopus laevis
… cellular division, the midblastula transition (MBT) begins and the cell cycle lengthens, acquiring gap phases. In addition, cell cycle checkpoint pathways and an apoptotic program become functional. The studies described here were performed to better understand the roles of two protein kinases, …

Influence of Bracket System on Smile Esthetics
… A survey compared Pitts™, Damon™, and 3M MBT™ prescription brackets. Photos of 18 treated cases (3 male and 3 female per system) were shown to 160 participants (100 laypeople and 60 orthodontists), who rated each smile from 1 (least esthetic) to 10 (most esthetic). RESULTS: Statistical …

Selenium-induced Enhancement of Hematoporphyrin Derivative Phototoxicity in Murine Bladder Tumor Cells
… derivative (Hpd) to murine bladder tumor (MBT-2) cells was studied in vitro. It was observed that selenium in the form of sodium selenite enhanced Hpd-sensitized photodamage in MBT-2 cells under conditions where the selenite alone was non-toxic. Sodium selenite was found to enhance the …

Asthma, caregiving and mental health : the mind keeps the score
… the use of Mentalisation-Based Treatment (MBT) in participants with different mental health presentations. The results suggest that MBT has strong evidence in the treatment of people with a diagnosis of Borderline Personality Disorder (BPD) and that MBT has the potential of improving …

A Comparative Analysis of Scenario Based Training and Maneuver Based Training in a 14 CFR part 141 Private Pilot Certification Course
… training, known as Maneuver Based Training (MBT), by utilizing scripted “real world” scenarios to introduce maneuvers and provide pilots in training with more decision making opportunities. Although variations of SBT have been used extensively in other fields such as the education, law …

NAT2TEST: generating test cases from natural language requirements based on CSP
… critical systems, and model based testing (MBT) techniques play an important role generating test cases from specification models. Concerning critical systems, these models are usually created using formal or semi-formal notations. Moreover, it is also desired to clearly and formally state …

Mechanisms of Action of Sulphur Containing Antioxidants
… study of the chemistry of mercaptobenzothiazole (MBT) and its zinc salt (ZMBT) in isolation from a rubber network and goes some way in explaining their antioxidant behaviour. Similar techniques to those used in Part A lead to the conclusion that decomposition products were again responsible for …

The integration of informal minibus-taxi transport services into formal public transport planning and operations - A data driven approach
The MiniBus Taxi (MBT) mode is poorly understood by planning and operational authorities, yet plays a big role in the economies of developing countries transporting the workforce to and from their places of employment and offering employment to thousands in the operations of these services, as well …

Studium fotodegradace piva optickými metodami
… zejména látka 3-methyl-2-buten-1-thiol (MBT). Vznik MBT je spojen s neenzymatickými reakcemi, v nichž vystupují isohumulony a sirné složky aminokyselin a jejich derivátů. Jako fotokatalyzátor zde působí riboflavin (vitamín B2), který absorbuje světelné záření a v excitovaném stavu reaguje …

Effects of Dextromethorphan on Neurite Outgrowth and Marble Burying Behavior
… OCD drugs include the marble-burying test (MBT) for compulsive behavior, in addition to the assessment of neurite outgrowth in PC12 cells. Therefore, to test the role of DM, a sigma-1 compound, glutamate NMDA antagonist, and DM metabolite-dextrorphan were used in both MBT and a neurite …

Should the City of Cape Town plan for fully autonomous vehicles?
… mainly private vehicles and minibus taxis (MBTs), which has contributed to Cape Town becoming the most congested city in South Africa. Autonomous vehicles have been touted as the elixir for the problems of road safety and congestion. Along with their ability to find the most efficient routes …

A study of potentially toxic elements in the Forth and Clyde Canal, Scotland, UK
… of methylmercury (Me-Hg), monobutyltin (MBT), dibutyltin (DBT) and tributyltin (TBT) were measured using GC-ICP-MS. Levels of Me-Hg (3.44 - 14.1 μg/kg) were < 0.58% of the pseudototal Hg content. The likely source is in situ bacteria-mediated methylation of inorganic Hg. Organotin mean …
