Diagnostic performance of depth of invasion, thickness, and styloglossus and hyoglossus muscle invasion on magnetic resonance imaging in predicting potential neck lymph node metastasis in clinical N0 tongue cancer.

Objectives: To evaluate previously reported quantitative (tumor thickness 11 mm and depth of invasion [DOI] 7.5 mm) and qualitative (styloglossus/hyoglossus muscle invasion [SHMI]) magnetic resonance imaging (MRI) parameters for predicting occult neck node metastasis in clinical N0 oral tongue squamous cell carcinoma.

Methods: This single-center retrospective study included 76 patients.

Endoscopic-assisted Maxillectomy and Fibular Flap Reconstruction: A Scarless Facial Approach With Novel Reconstruction and Operative Techniques Avoiding Facial Skin Incision.

The facial approach remains a challenge in maxillectomy and reconstruction. Various surgical approaches have been developed to improve cosmetic outcomes. The authors herein present a novel approach for endoscopic-assisted maxillectomy with minimal facial incision and endoscopic-assisted vascularized fibular osteomyocutaneous flap (VFOF) reconstruction.

Synthesis of Bimetallic Dinuclear Hydrido Complexes of Re and Rh/Ir Supported by a Direct M-M' Bond: The Role of the M-M' Bond in the Site Exchange of Hydrides.

Heterometallic tetrahydrido complexes [Cp*Re(H)(μ-H)MCp*] (: M = Ir, : M = Rh) were synthesized by the reaction of [Cp*ReH] and [Cp*M(sol)] (M = Ir, Rh) followed by deprotonation. Although possesses four hydrides and adopts a 30-electron configuration as [Cp*Ru(μ-H)RuCp*] () does, the positions of the hydrides in differ from those in : two terminal and two bridging hydrides. In addition, adaptive natural density partitioning (AdNDP) analysis demonstrated that a direct Re-M bond is held in .

Biallelic missense CEP55 variants cause prenatal MARCH syndrome.

CEP55 encodes centrosomal protein 55 kDa, which plays a crucial role in mitosis, particularly cytokinesis. Biallelic CEP55 variants cause MARCH syndrome (multinucleated neurons, anhydramnios, renal dysplasia, cerebellar hypoplasia and hydranencephaly). Here, we describe a Japanese family with two affected siblings harboring novel compound heterozygous CEP55 variants, NM_001127182: c.
