Timing of Cleft Palate Repair in Patients With and Without Robin Sequence.

Background: This cohort study aimed to assess how age at repair affects outcomes in nonsyndromic patients with and without Robin Sequence using a national database of commercial healthcare claims.

Methods: Children under 4 years of age undergoing palatoplasty were identified in the IBM MarketScan Commercial Database based on ICD-9-CM and CPT procedure codes. They were divided into Robin and non-Robin cleft palate groups, and further divided by time of initial cleft palate repair: Robin Sequence into 2 groups: age ≤10 months or >10 months; non-Robin cleft palate into 3 groups: age ≤10 months, >10-14 months, or >14 months age.

Algorithm for Management of Mandibular Condylar Base Fractures.

Background: Increasing evidence suggests that open reduction and internal fixation of condylar base fractures in adults results in improved outcomes in regard to interincisal opening, jaw movement, pain, and malocclusion. However, most of the condylar fractures are managed by maxillomandibular fixation alone due to the need for specialized training and equipment. Our aim was to present an algorithm for condylar base fractures to simplify surgical management.

Induction of regulatory T-cells from memory T-cells is perturbed during acute exacerbation of multiple sclerosis.

Regulatory T-cells (Tregs) are vital for maintaining immunological self-tolerance, and the transcription factor FOXP3 is considered critical for their development and function. Peripheral Treg induction may significantly contribute to the total Treg pool in healthy adults, and this pathway may be enhanced in thymic-deficient conditions like multiple sclerosis (MS). Here, we evaluated iTreg formation from memory versus naïve CD4(+)CD25(-) T-cell precursors.

Disease exacerbation of multiple sclerosis is characterized by loss of terminally differentiated autoregulatory CD8+ T cells.

Multiple sclerosis (MS) is an inflammatory, demyelinating disease of the central nervous system (CNS). Although its etiology remains unknown, pathogenic T cells are thought to underlie MS immune pathology. We recently showed that MS patients harbor CNS-specific CD8+ Tregs that are deficient during disease relapse.

Quantitative profiling and pattern analysis of triacylglycerol species in Arabidopsis seeds by electrospray ionization mass spectrometry.

Plant triacylglycerols (TAGs), or vegetable oils, provide approximately 25% of dietary calories to humans and are becoming an increasingly important source of renewable bioenergy and industrial feedstocks. TAGs are assembled by multiple enzymes in the endoplasmic reticulum from building blocks that include an invariable glycerol backbone and variable fatty acyl chains. It remains a challenge to elucidate the mechanism of synthesis of hundreds of different TAG species in planta.
