Se evaluó la inclusión de una premezcla alimenticia de ingredientes no convencionales (PM-INC) en base a lupino, vicia, linaza y trigo como parte del lacto-reemplazante (LR). Se trabajó con 24 terneros machos Holstein cruzados recién nacidos, distribuidos en tres tratamientos: T1: leche entera (LE), T2 (LR-LDMC): LR con 80% leche descremada (LD) + 20% manteca de cerdo, T3 (LR-LDINC): LR con 75% LD + 25% PM-INC. La LE y LR fueron suministrados dese el inicio del experimento hasta el destete (ocho semanas), el alimento iniciador se suministró desde la segunda semana y de heno de alfalfa desde la sexta semana. No se observaron diferencias significativas entre tratamientos para consumo de alimento, peso vivo, ganancias de peso, ni altura a la cruz. Sin embargo, se encontró un menor costo de ternero destetado por concepto de alimentación en el tratamiento LR-LDINC equivalente a S/. 13.37 menos respecto del tratamiento LE y S/. 13.51 menos respecto del tratamiento LR-LDMC. Se concluye que el ternero macho Holstein cruzado de la zona altoandina de Cajamarca responde satisfactoriamente al suministro de un LR conteniendo 75% LD + 25% PMINC en fase de cría durante 56 días.

Abstract
BackgroundThe occurrence of skeletal metastases of unknown primary origin (SMUP) is uncommon. To provide appropriate treatments for the primary and metastatic lesions, early diagnosis of the primary origin of SMUP is important. Therefore, this study aimed to assess the types of examination method effective in diagnosing the primary origin of SMUP and their order in terms of efficacy.MethodsWe retrospectively examined 63 patients with SMUP. The primary origin was examined via physical examination, blood test including tumor markers, chest radiography, thoracoabdominal computed tomography (CT) scan, positron emission tomography (PET)-CT scan, metastatic lesion biopsy, and other assessments. Examination methods considered effective for the diagnosis of the primary origin in a specific type of cancer were investigated.ResultsThe lung was the most common primary origin, followed by the lymph nodes, prostate, and breast. Meanwhile, biopsy (87.0%) was the most effective examination, followed by PET-CT scan (60.0%) and thoracoabdominal CT scan (38.6%). The first four steps; physical examination, blood tests, chest radiography, thoracoabdominal CT were effective in diagnosing the primary origin in 41 (65%) of 63 patients. Finally, four patients were diagnosed with SMUP.ConclusionsThe examination steps used in this study are effective in diagnosing the primary origin of SMUP during the initial visit. Blood tests are useful for hematological malignancy and prostate cancer. CT scan can be used to identify cancers in the lung, breast, and kidney, which are the common primary origins. Moreover, it is more useful than PET-CT scan from a comprehensive perspective.

Abstract
Background: Traumatic arrests (TA) increasingly affect young adults worldwide with low reported survival rates. This study examines factors associated with survival (to hospital discharge) in traumatic arrests transported to US trauma centers. Methods: This retrospective cohort study used the US National Trauma Databank 2015 dataset and included patients who presented to trauma centers with “no signs of life”. Univariate and bivariate analyses were done. Factors associated with survival were identified using multivariate regression analyses. Results: The study included 5,980 patients with traumatic arrests. Only 664 patients (11.1%) survived to hospital discharge. Patients were predominantly in age group 16-64 (84.6%), were mostly males (77.8%) and white (55.1%). Most were admitted to Level I (55.5%) or Level II trauma centers (31.6%). Injuries were mostly blunt (56.7%) or penetrating (39.3%). Mean ISS was 23.71 (± 20.79). Factors associated with decreased survival included: Age group ≥65 (Ref: 16-24), male gender, self-inflicted and other or undetermined types of injuries (Ref: assault), injuries to head & neck, injuries to torso and injury severity score (ISS) ≥ 16 (Ref: <16). While factors associated with increased survival included: All injury mechanisms (with the exception of Motor Vehicle Transportation (MVT)) (Ref: firearm), injuries to extremities or spine & back and all methods of coverage (Ref: self-pay).Conclusion: Patients with traumatic arrests have poor outcomes with only 11.1 % surviving to hospital discharge. Factors associated with survival in traumatic arrests were identified. These findings are important for devising injury prevention strategies and help guide trauma management protocols to improve outcomes in traumatic arrests. Level of evidence: Level III

Abstract
With the motive of unraveling the effect of Cr incorporation on the structural, microstructural, dielectric, ferroelectric, energy storage, and magnetic properties of BCT (Barium Calcium Titanate) ceramics have been investigated. Ba0.80Ca0.20Ti1-3x/4CrxO3 (0.000 ≤ x ≤ 0.020) powder samples have been prepared using classical solid-state reaction method. Cr doped BCT ceramics showed a single phase perovskite structure having a tetragonal phase without phase transformation from P4mm to Pm-3m after the addition of Cr. With increased Cr content, the tolerance factor, lattice parameters, unit cell volume, c\a ratio, and grain size have been found to decrease. Both Debye-Scherrer and Williamson-Hall plot methods confirmed the reduction of crystallite size on increased Cr doping in BCT lattice. A dielectric anomaly “hump” (̴ 447 K) has been observed at low frequencies in the paraelectric region due to the presence of acceptor induced defect dipoles. The temperature-dependent dielectric properties of prepared BCT ceramic with Cr compositions possess diffused phase transition (DPT) and the width of DPT is increased. Room temperature energy storage density achieved the maximum value of 190.35 mJ/cm3 for the composition x = 0.005 at an electric field of 55 kV/cm. For the Cr composition of x = 0.015 and an electric field of 10 kV/cm, the highest energy storage efficiency (η) of about 60.5 % has been obtained at room temperature. % Temperature coefficient of capacitance has been obtained to vary between ± 15 % in the temperature range of 303 K to 523 K. Cr doped ceramic samples exhibit room temperature ferromagnetism at low magnetic fields and diamagnetism at a higher value of magnetic fields. These results suggest prepared ceramics as a suitable lead-free material for X8R multilayer ceramic capacitor devices and energy applications.

Abstract
Yttrium orthoferrite (YFeO3) is of considerable interest for its potential application in magnetic field sensors and magneto optical data storage devices. Doping is one of the effective approaches to tune the compound properties. And it is important to determine the doping sites of the dopants to better understanding the related mechanism. In this work, Manganese (Mn) doped YFeO3, i.e., YFMxO powders with 0 ≤ x ≤ 0.1 were synthesized by hydrothermal method to study the influences of doping on their structural, morphological, local electrical, optical and magnetic properties. The experimental results show that Mn dopants occupy Iron (Fe) sites and that all these samples exhibit an orthorhombic structure with space group Pnma. Refined structure parameters are presented. Morphology images show the shape evolution from layered to multilayered with increasing Mn content. The Fe and Y K-edge local structure studies indicate that the valency of Fe and Y is mainly found in trivalent state, which also indicate that substitution of Mn ions not only affects the nearest neighbor atomic shell of Fe but also affects the nearest neighbor’s local structure of Y atoms. IR spectra reveal the characteristic vibrations of the obtained YFMxO samples. From the magnetic study, it is observed that the substitution of Y ions by Mn ions changes the magnetic property of YFeO3 from ferromagnetic to paramagnetic. Our results show that the addition of Mn exhibits an evident influent on the local structural and magnetic properties.

Abstract
Background
Complex developmental encephalopathy syndromes might be the consequence of unknown genetic alterations are likely to contribute to the full neurological phenotype as a consequence of pathogenic gene combinations.
Methods
To identify the additional genetic contribution to the neurological phenotype, we studied as a test case a boy, with a KCNQ2 exon-7 partial duplication, by single nucleotide polymorphism (SNP) microarray to detect copy-number variations (CNVs).
Results
The proband presented a cerebral palsy like syndrome with a severe motor and developmental encephalopathy. The SNP array analysis detected in the proband several de novo CNVs, nine partial gene losses (LRRC55, PCDH9, NALCN, RYR3, ELAVL2, CDH13, ATP1A2, SLC17A5, ANO3), and two partial gene duplications (PCDH19, EFNA5). The biological functions of these genes are associated with ion channels such as calcium, chloride, sodium, and potassium; and with several membrane proteins implicated in neural cell-cell interactions, synaptic transmission and axon guidance. Pathogenically, these functions can be associated to cerebral palsy, seizures, dystonia, epileptic crisis, and motor neuron dysfunction, all present in the patient.
Conclusions
Severe motor and developmental encephalopathy syndromes of unknown origin can be the result of a phenotypic convergence by combination of several genetic alterations in genes whose physiological function contributes to the neurological pathogenic mechanism.

Abstract
Introduction: We sought to investigate the distribution of traditional Chinese medicine (TCM) syndromes and their elements among bronchiectasis patients using real-world data. Methods: A real-world study was performed to explore the relationship between TCM syndrome and bronchiectasis using electronic medical information from 1,113 patients in China. Factor analyses were used to reduce the dimensions of TCM syndrome elements and to detect common factors. Additionally, cluster analyses were employed to assess combinations of TCM syndrome elements. Finally, association rule analyses were performed to investigate the structures of TCM syndrome elements in order to estimate the patterns of TCM syndromes.Results: A total of 17 TCM syndrome elements were extracted using this method. There were four Shi TCM syndromes of Tan_Re_Yong_Fei (36.39%), Tan_Zhuo_Zu_Fei (12.94%), Gan_Huo_Fan_Fei (11.59%), and Feng_Re_Fan_Fei (11.32%) with >5.0% distribution frequency in total sample. The highest Xu TCM syndrome was Fei_Yin_Xu (18.24%). Factor analysis, cluster analysis, and association rule analysis found that Tan, Huo, Feng, Yin_Xu, Fei, and Gan were the core TCM syndrome elements.Conclusion: In this study, TCM Shi syndromes of Tan_Re_Yong_Fei, Tan_Zhuo_Zu_Fei, Gan_Huo_Fan_Fei, and Feng_Re_Fan_Fei were detected with a high frequency among bronchiectasis patients using real-world data, as was the TCM core Xu syndrome of Fei_Yin_Xu. The core elements of Huo, Tan, Feng, Yin_Xu, Fei and Gan were found across the entire sample.

Abstract
Bacterial cellulose (BC) has profound applications in different sectors of biotechnology due to its unique properties preferring it about plant cellulose. Although this polymer is extremely important in various applications, many problems still hinder the sustainable production in terms of increasing productivity and low-cost production. In order to overcome these problems, this study will focuses on the continuous production of cellulose using immobilized Glucanobacter xylinum cells onto Sugar Cane Bagasse (SCB) and Ca-alginate beads. Comparatively, adsorption of Glucanobacter xylinum cells to the cavum of stalk cells of SCB could be efficiently stable while, entrapment of cells onto Ca-alginate has drawback observed by the rapid disruption and instability of the beads in the Potato Peel Waste (PPW) culture medium. Our findings demonstrate that a combination between alternative low-cost medium with continuous production mode by immobilization onto inexpensive natural polymer can promote a sustainable bioprocess and reduction the production cost.

Abstract
Environmental toxic waste from heavy metals along with minerals within the waste matter is one of the most significant issue in an Asian country. The activities like industrial operations particularly mining, agricultural processes and disposal of industry waste materials; their concentration has redoubled to hazardous levels. Major metals in industrial sewage represent Cu, Cr3+and Pb etc. So far, varieties of inexpensive strategies are reviewed for the removal of these metals. The various processes include chemical precipitation, reverse diffusion, electro qualitative analysis, nanofiltration and floatation. But these strategies have many disadvantages like high chemical agent demand, unpredictable metal particle elimination, and production of unhealthful sludge. Surface absorption method being terribly straightforward, economical, effective and versatile has become the most popular strategies for removal of unhealthful contaminants from waste matter. This paper gives a new idea for the utilization of natural materials as adsorbents for significant metal removal from industrial waste water. The components used are mustard plant roots, human hair and some common house hold waste products such as, egg shell and coconut shell. Utilizing their adsorbent properties in an efficient way, it can be used to filter industrial heavy metals which cause pollution.
