A ROCK inhibitor promotes keratinocyte survival and paracrine secretion, enhancing establishment of primary human melanocytes and melanocyte‐keratinocyte co‐cultures
Abstract Primary melanocytes isolated from skin and expanded in culture have been widely used for laboratory research and clinical applications. The conventional method to isolate primary melanocytes from skin usually requires about 3 to 4 weeks of culture for melanocytes to grow sufficiently to passage. Considering that melanocytes comprise only 3‐7% of epidermal cells in normal human skin, it would be extremely helpful to increase the isolation efficiency and shorten the initial culture time to...

Convolutional neural networks for reconstruction of undersampled optical projection tomography data applied to in vivo imaging of zebrafish
ABSTRACT Optical projection tomography (OPT) is a 3D mesoscopic imaging modality that can utilize absorption or fluorescence contrast. 3D images can be rapidly reconstructed from tomographic data sets sampled with sufficient numbers of projection angles using the Radon transform, as is typically implemented with optically cleared samples of the mm‐to‐cm scale. For in vivo imaging, considerations of phototoxicity and the need to maintain animals under anesthesia typically preclude the acquisition...

Generalized spectral light scatter models of diverse bacterial colony morphologies
ABSTRACT An optical forward‐scatter model was generalized to encompass the diverse nature of bacterial colony morphologies and the spectral information. According to the model, the colony shape and the wavelength of incident light significantly affect the characteristics of a forward elastic‐light‐scattering pattern. To study the relationship between the colony morphology and the scattering pattern, 3‐dimensional colony models were generated in various morphologies. The propagation of light passing...

A comparative study of litter size and sex composition in a large dataset of callitrichine monkeys
Sibling competition shapes survival and reproductive outcomes in captive callitrichine monkeys. Abstract In many birds and mammals, the size and sex composition of litters can have important downstream effects for individual offspring. Primates are model organisms for questions of cooperation and conflict, but the factors shaping interactions among same‐age siblings have been less‐studied in primates because most species bear single young. However, callitrichines (marmosets, tamarins, and lion...

Unmasking the Masquerader: A Delayed Diagnosis of MS and Its 4.5 Years of Implications in an Older African American Male
Multiple sclerosis (MS) has classically been described as a disease of the young Caucasian female. While the prevalence may seem to be higher in Caucasians (CAs), recent studies suggest that the real incidence of MS may actually be higher in African Americans (AAs). Here, we discuss a nonclassical case of MS in an older African American male, prognostic factors, disease patterns in African Americans, and how a delay in diagnosis and socioeconomic factors can lead to worse outcomes. In patients that...

Phosphite Catalyzed C–H Allylation of Azaarenes via an Enantioselective [2,3]‐Aza‐Wittig Rearrangement
A phosphite mediated [2,3]‐aza‐Wittig rearrangement has been developed for the regio‐ and enantioselective allylic alkylation of six‐membered hetero‐aromatic compounds (azaarenes). The nucleophilic phosphite adduct of N‐allyl salts undergoes a stereoselective base mediated aza‐Wittig rearrangement and dissociation of the chiral phosphite for overall C–H functionalization of azaarenes. This method provides efficient access to tertiary and quaternary chiral centers in isoquinoline, quinoline,...

Polymeric Encapsulation of Novel Homoleptic Bis(dipyrrinato) Zinc(II) Complexes with Long Lifetimes for Applications as Photodynamic Therapy Photosensitisers
The use of photodynamic therapy (PDT) to treat various types of cancer has received increasing attention over the last years. However, the clinically used photosensitisers (PSs) have some limitations that include poor aqueous solubility, hepatotoxicity, photobleaching, aggregation and slow clearance from the body, leading to photosensitivity. To circumvent these drawbacks, the design of new classes of PSs is of high interest. Herein, we present the first example of the use of bis(dipyrrinato)zinc(II)...

Tunable hydrogen release from amine‐boranes via their insertion into functional polystyrenes
Polystyrene‐g‐boramines random copolymers are dihydrogen reservoirs with tunable dehydrogenation temperatures, which can be adjusted by selecting the boramine content in the copolymers. They display a unique dihydrogen thermal release profile, which is a direct consequence of the insertion of the amine‐boranes in a polymeric scaffold, and not from a direct modification of the electronics or sterics of the amine‐borane function. Finally, the mixture of polystyrene‐g‐boramines with conventional NH3‐BH3...

Bridging crystal engineering and drug discovery by utilizing intermolecular interactions and molecular shapes in crystals
Most structure‐based drug discovery protocols utilize crystal structures of receptor proteins. Crystal engineering, on the other hand, utilizes the wealth of chemical information inherent in small‐molecule crystal structures in the Cambridge Structural Database (CSD). Here we show that interaction surfaces and shapes of molecules in experimentally determined small‐molecule crystal structures can serve as effective tools in drug discovery.

Identification of a Dominant MYH11 Causal Variant in Chronic Intestinal Pseudo‐Obstruction: Results of Whole‐Exome Sequencing
Abstract Chronic Intestinal Pseudo‐Obstruction (CIPO) is a rare gastrointestinal disorder, which affects the smooth muscle contractions of the gastrointestinal tract. Dominant mutations in the smooth muscle actin gene, ACTG2, accounts for 44‐50% of CIPO patients. Other recessive or X‐linked genes, including MYLK, LMOD1, RAD21, MYH11, MYL9, and FLNA were reported in single cases. In this study, we used Whole‐Exome Sequencing (WES) to study 23 independent CIPO families including one extended...

Efficacy of Transnasal Flexible Videoendoscopy With Narrow Band Imaging for Follow‐Up of Patients After Transoral Laser Cordectomy
Background and Objectives Transoral laser surgery is the optimal surgical treatment modality for the early stages of glottic cancer. To allow for further treatment to be as effective and as minimal as possible, persistent or recurrent tumors should be detected very soon. The main aim is to minimize the risk of necessity of performing a total laryngectomy. Flexible videoendoscopy with narrow band imaging (NBI) was recommended by the European Laryngological Society as a diagnostic method for the follow‐up...
