Migraine is the third most common disease in the world (behind dental caries and tension-type headache) with an estimated global prevalence of 15%, yet its etiology remains poorly understood. Recent clinical trials have heralded the potential of therapeutic antibodies that block the actions of the neuropeptide calcitonin gene-related peptide (CGRP) or its receptor to prevent migraine. CGRP is believed to contribute to trigeminal nerve hypersensitivity and photosensitivity in migraine, but a direct role in pain associated with migraine has not been established...

Even with state-of-the-art techniques there are individuals whose paralysis prevents them from communicating with others. Brain⁻Computer-Interfaces (BCI) aim to utilize brain waves to construct a voice for those whose needs remain unmet. In this paper we compare the efficacy of a BCI input signal, code-VEP via Electroencephalography, against eye gaze tracking, among the most popular modalities used. These results, on healthy individuals without paralysis, suggest that while eye tracking works well for some, it does not work well or at all for others; the latter group includes individuals with corrected vision or those who squint their eyes unintentionally while focusing on a task...

REVIEW
Ji-Hyun Lee, Giwoong Hong
Clarification is needed regarding the definitions and classification of groove and hollowness of the infraorbital region depending on the cause, anatomical characteristics, and appearance. Grooves in the infraorbital region can be classified as nasojugal grooves (or folds), tear trough deformities, and palpebromalar grooves; these can be differentiated based on anatomical characteristics. They are caused by the herniation of intraorbital fat, atrophy of the skin and subcutaneous fat, contraction of the orbital part of the orbicularis oculi muscle or squinting, and malar bone resorption...

Acute compartment syndrome (ACS) is a surgical emergency that requires urgent fasciotomy to prevent irreversible sequelae. We report two cases of unidentified ACS, which did not result from traumatic injuries such as fractures or crush injury, iatrogenic injury or diseases such as haematological malignancies. Both patients complained of severe pain and swelling of their extremity. No bite marks, blisters or skin necrosis was noted. They also complained of marked symptoms of third cranial nerve injury, including divergent squint and diplopia...

BACKGROUND: Strabismus, or squint, can be defined as a deviation from perfect ocular alignment and can be classified in many ways according to its aetiology and presentation. Treatment can be broadly divided into medical and surgical options, with a variety of surgical techniques being available, including the use of adjustable or non-adjustable sutures for the extraocular muscles. There exists an uncertainty as to which of these techniques produces a better surgical outcome, and an opinion that the adjustable suture technique may be of greater benefit in certain situations...

Min Liu, Zhou Li, Lu Liu
Sidelobe reduction is a very primary task for synthetic aperture radar (SAR) images. Various methods have been proposed for broadside SAR, which can suppress the sidelobes effectively while maintaining high image resolution at the same time. Alternatively, squint SAR, especially highly squint SAR, has emerged as an important tool that provides more mobility and flexibility and has become a focus of recent research studies. One of the research challenges for squint SAR is how to resolve the severe range-azimuth coupling of echo signals...

INTRODUCTION: The tear trough deformity is commonly requested for correction, most often by filler injections. However, the tear trough remains difficult to treat due to its complex anatomy, a variety of other concurrent deformities, and the high risk of complications. OBJECTIVES: To create a standardized categorization, evaluation, and treatment protocol for the management of tear troughs with fillers. METHODS: (1) Patient deformity profiles are determined using three categories of traits: A (Atrophy), B (Bulging), L (Laxity)...

Thymic carcinoma with central nervous system involvement is very rare in children. A 27-month-old girl presented with a unilateral squint, vomiting, and behavioral changes. Imaging studies showed a silent anterior mediastinal mass and a large metastatic mass at the base of the skull. Biopsy of the anterior mediastinal mass confirmed an undifferentiated tumor consistent with thymic carcinoma. The child died within 3 months of the onset of symptoms, due to progression of the disease. These lethal tumors of unknown histogeneses and etiology are aggressive in nature, resistant to therapy, and have a rapidly fatal course...

Persistent Hyperplastic Primary Vitreous (PHPV), now-a-days referred to as Persistent Fetal Vasculature (PFV), is a rare congenital anomaly of the eye that typically presents unilaterally with white pupillary reflex and microphthalmia without systemic associations. Bilateral presentations are rare. Here we report a case of 15-year-old male with bilateral PFV without leucokoria who was misdiagnosed as congenital esotropia with amblyopia, treated for refractive errors and referred to higher centre for squint corrections...

Vertebrate embryonic patterning depends on signaling from Nodal, a TGFβ superfamily member. There are three Nodal orthologs in zebrafish; southpaw directs left-right asymmetries, while squint and cyclops function earlier to pattern mesendoderm. TGFβ member Vg1 is implicated in mesoderm formation but the role of the zebrafish ortholog, Growth differentiation factor 3 (Gdf3), has not been fully explored. We show that zygotic expression of gdf3 is dispensable for embryonic development, while maternally deposited gdf3 is required for mesendoderm formation and dorsal-ventral patterning...

Tianzhu Yi, Zhihua He, Feng He, Zhen Dong, Manqing Wu
This paper presents a modified approach for high-resolution, highly squint synthetic aperture radar (SAR) data processing. Several nonlinear chirp scaling (NLCS) algorithms have been proposed to solve the azimuth variance of the frequency modulation rates that are caused by the linear range walk correction (LRWC). However, the azimuth depth of focusing (ADOF) is not handled well by these algorithms. The generalized nonlinear chirp scaling (GNLCS) algorithm that is proposed in this paper uses the method of series reverse (MSR) to improve the ADOF and focusing precision...

Introduction: Ectopia lentis is defined as a crystalline lens displacement, either partially or completely, due to zonular abnormalities. It can be a result of trauma, hereditary ocular disease, or part of systemic diseases, like Marfan syndrome and homocystinuria. Case description: We report a case of a medically free 16-year-old girl, who was referred to our hospital complaining of poor vision and a squint in both eyes since childhood. Her history included a traffic accident when she was one-year-old. She was previously diagnosed with alternating esotropia, which was treated with glasses, alternating patching, and bilateral Botox injections...

In many organisms, transcriptional and post-transcriptional regulation of components of pathways or processes has been reported. However, to date, there are few reports of translational co-regulation of multiple components of a developmental signaling pathway. Here, we show that an RNA element which we previously identified as a dorsal localization element (DLE) in the 3'UTR of zebrafish nodal-related1/squint (ndr1/sqt) ligand mRNA, is shared by the related ligand nodal-related2/cyclops (ndr2/cyc) and the nodal inhibitors, lefty1 (lft1) and lefty2 mRNAs...
