Camera re-calibration after zooming based on sets of conics
We describe a method to compute the internal parameters (focal and principal points) of a camera with known position and orientation, based on the observation of two or more conics on a known plane. The conics can even be degenerate (e.g. pairs of lines). The proposed method can be used to re-estimate the internal parameters of a fully calibrated camera after zooming to a new, unknown, focal length. It also allows estimating the internal parameters when a second, fully calibrated camera observes the same conics. The parameters estimated through the proposed method are coherent with the output of more traditional procedures that require a higher number of calibration images. A deep analysis of the geometrical configurations that influence the proposed method is also reported
Pengaruh Pemberian Probiotik sebagai Aditif Pakan terhadap Kadar Kolesterol, High Density Lipoprotein (Hdl) dan Low Density Lipoprotein (Ldl) dalam Darah Ayam Kampung
Probiotic is a supllement feed mikrobia which beneficial for cattle to keep mikrobia balance in gut. Giving probiotic can keep the composition mikrobia in digestive tract of cattle to increase the power of gastrointestinal tract and keep healty of cattle. The aims of research was to measure the levels of cholesterol, HDL and LDL in blood of indigenous chicken with given as probiotics feed additive. This study used Day Old Chick (DOC) of 200 chicken with initial body weight of an average of 33.58 ± 0.8 grams, antikoagulen, EDTA, Vacuntainer, Centrifuge. Probiotics used which are the kind of mold. The composition of basal feed are metabolizable energy (ME) 2750 kcal, 20.9% crude protein, 6.260% fat. Experimental design used was completely randomized design (CRD) consisting of 4 treatments with 5 replicates, each experimental unit 20. The treatment was dose of probiotic T0 without probiotics addition, applied 0.25 g probiotic / 100 g (T1), 0.50 g probiotic / 100 (T2), 0.75 g probiotic / 100 g (T3). The results showed that addition of probiotics affected (P <0.05) to the levels of Cholesterol, HDL, LDL. The average HDL levels each treatment T0, T1, T2 and T3 were 41,440; 45,920; 48,440 and 50,440 mg/dl respectively. The average LDL levels each treatment T0, T1, T2 and T3 were 78,089; 70,550; 45,677; and 47,011 mg/dl respectively. The average Cholesterol levels each treatment T0, T1, T2 and T3 were 163,529; 160,000; 132,941; and 131,764 mg/dl respectively. The emelutions the addition of probiotics increased levels of HDL, decreased levels of LDL and cholesterol in indigenous chickens
Linear pose estimate from corresponding conics
We propose here a new method to recover the orientation and position of a plane by matching at least three projections of a conic lying on the plane itself. The procedure is based on rearranging the conic projection equations such that the non linear terms are eliminated. It works with any kind of conic and does not require that the shape of the conic is known a-priori. The method was extensively tested using ellipses, but it can also be used for hyperbolas and parabolas. It was further applied to pairs of lines, which can be viewed as a degenerate case of hyperbola, without requiring the correspondence problem to be solved first. Critical configurations and numerical stability have been analyzed through simulations. The accuracy of the proposed algorithm was compared to that of traditional algorithms and of a trinocular vision system using a set of landmarks
TIE-2 expressing monocytes in human cancers.
Tumor-associated macrophages (TAM) are well known as a key player in the tumor microenvironment, which support cancer progression. More recently, a lineage of monocytes characterized by the expression of the TIE-2/Tek angiopoietin receptor identified a subset of circulating and tumor-associated monocytes endowed with proangiogenic activity. TIE-2 expressing monocytes (TEM) were found both in humans and mice. Here, we review the phenotypes and functions of TEM reported so far in human cancer and their potential use as markers of cancer progression and metastasis. Finally, we discuss the therapeutic approaches currently used or proposed to target TEM
Wernicke encephalopathy caused by avoidance-restrictive food intake disorder in a child: a case-based review
Background: Wernicke encephalopathy (WE) is an acute and potentially fatal neuropsychiatric disorder resulting from thiamine deficiency: its etiology and clinical presentation can be heterogeneous and arduously recognized, especially in children and adolescents. Case presentation: An 8-year-old girl arrived to the emergency room with ataxic gait, nystagmus, and mental confusion after a 10-day history of repeated severe vomiting; her recent clinical history was characterized by restricted nutrition due to a choking phobia, which caused substantial weight loss. Brain magnetic resonance imaging revealed a bilaterally increased T2 signal in the medial areas of the thalami and cerebral periaqueductal region. Diagnosis of WE based on clinical and neuroradiological findings was established and confirmed after labwork showing low serum thiamine. Following psychiatric evaluation, the patient was also diagnosed with avoidance-restrictive food intake disorder (ARFID), which required starting cognitive behavioral therapy and introducing aripiprazole. The patient displayed improvement of the radiological findings after one month and complete resolution of her neurological symptoms and signs. Conclusions: Eating disorders like ARFID might forerun acute signs of WE; this possibility should be considered even in pediatric patients, especially when atypical neurological pictures or feeding issues come out

Luteinizing Hormone/Human Chorionic Gonadotropin Receptor Immunohistochemical Score Associated with Poor Prognosis in Endometrial Cancer Patients.
The aim of this study was to develop a scoring system of the immunohistochemical (IHC) expression of luteinizing hormone/human chorionic gonadotropin receptor (LHCG-R) in endometrial cancer (EC) patients. Nonconsecutive hysterectomy specimens containing EC collected from April 2013 to October 2015 were selected. Hematoxylin-eosin stained sections from each case were reviewed and representative sections from each tumor were selected. IHC staining was performed for the detection of LHCG-R. The percentage of stained cells and the staining intensity were assessed in order to develop an immunohistochemical score. Moreover, we examined the correlation of the score with grading and lymphovascular space invasion (LVSI). There was a statistically significant positive correlation between grading and IHC scoring (p=0.01) and a statistically significant positive correlation between LVSI and IHC score (p<0.01). In conclusion, we suggest that the immunohistochemical score presented here could be used as a marker of bad prognosis of EC patients. Nevertheless, further studies are needed in order to validate it. The study was registered in the Careggi Hospital public trials registry with the following number: 2013/0011391
