The (In 1−x Fe x ) 2 O 3 films (0 ≤ x ≤ 0.09) were prepared by RF-magnetron sputtering. Structural, magnetic and transport properties of the films were investigated systematically both experimentally and theoretically. X-ray absorption spectroscopy (XAS) and multiple-scattering ab initio theoretical calculations reveal that Fe dopant atoms are substitutionally incorporated into In 2 O 3 lattice with a mixed-valence (Fe 2+ /Fe 3+ ) and form Fe In1 +2 V O complex. All the films display room temperature ferromagnetism and the saturated magnetization (M s ) increases monotonically with the increase of Fe concentration. The Mott variable range hopping (VRH) transport behavior dominates the conduction mechanism of the films at low temperature, confirming that the carriers are localized. The Fe doping has profound effects on the positive and negative MR contributions. The positive MR contribution becomes more pronounced with Fe doping, reflecting the occurrence of spin polarization and stronger s−d exchange interaction. The bound magnetic polarons (BMPs) associated with oxygen vacancy can be considered to play an important role in achieving the ferromagnetic order of the (In 1−x Fe x ) 2 O 3 films. The variation of Ms with Fe doping has a strong correlation with the localization radius ξ of carriers and the characteristic hopping temperature T 0 , indicating that the change of localization effect can remarkably influence the ferromagnetic order of the (In 1−x Fe x ) 2 O 3 films.

ABSTRACT. Warm day and cool night conditions significantly induce reproductive spike formation in Phalaenopsis plants; hence, determining the flowering mechanism regulating the reproductive transition is important. Flowering locus T (FT) plays important roles in flowering induction in several plants. To explore spike induction by warm days and cool nights in Phalaenopsis orchids, we isolated the FT (PhFT) from Phalaenopsis hybrid Fortune Saltzman. The cDNA of PhFT was 809-bp long and contained a 531-bp open reading frame encoding a putative protein of 176 amino acids, a 58-bp 5'-untranslated region (UTR), and a 220-bp 3'-UTR. The predicted molecular mass of PhFT was 19.80 kDa, with an isoelectric point of 8.68. The PhFT was predicted to possess the conserved functional regions of the phosphatidylethanolamine-binding protein superfamily. Nucleotide sequence data indicated that PhFT contained 3 introns and 4 exons. Sequence alignment and phylogenetic analyses of PhFT revealed high homology to the FT proteins of Cymbidium goeringii and Oncidium Gower Ramsey. Quantitative realtime polymerase chain reaction analysis indicated that PhFT mRNA Functional characterization of a PhFT gene was expressed in roots, apical leaves, mature leaves, and flowers. In flowers, PhFT was expressed more in developing floral buds than in mature flowers and was predominantly expressed in ovaries and petals. Ectopic expression of PhFT in Arabidopsis ft-1 mutants showed novel early-flowering phenotypes that lost their siliques. Our results indicated that the ectopic expression of PhFT could partially complement the late flowering defect in transgenic Arabidopsis ft-1 mutants. Our findings suggest that PhFT is a putative FT homolog in Phalaenopsis plants that regulates flowering transition.

IntroductionLaparoscopic colorectal resection is becoming the gold standard for treating colorectal cancers because it offers superior short‐term and comparable long‐time outcomes compared to open surgery. Intraoperative colonoscopy (IOC) is increasingly performed for tumor localization and mucosal assessment. The aim of this report was to review the safety and efficacy of IOC in laparoscopic colorectal surgery.MethodA MEDLINE search of studies of IOC in laparoscopic colorectal surgery was performed. We focused on three aspects of IOC use: (i) IOC for intraoperative tumor localization; (ii) colonic irrigation and IOC for obstructive left‐sided colorectal cancers; and (iii) IOC for assessing colorectal anastomosis.ResultsDuring laparoscopic colorectal surgery, IOC enables accurate localization of early mucosal tumors, detection of lesions in the proximal unexamined colon for obstructive left‐sided cancer, and visual assessment of anastomosis. Additionally, IOC allows for proper surgical resection, management of concomitant lesions, immediate maintenance of hemostasis, suture repair of leaks, and the creation of a protective stoma as necessary.ConclusionsIntraoperative colonoscopy is beneficial in laparoscopic colorectal surgery. Experienced surgical endoscopists should be trained to safely perform IOC.

An asymptomatic pulmonary mass was found in a 42-year-old unmarried male with controlled nasopharyngeal carcinoma (NPC) during routine follow-up chest radiography 8 months following completion of radiotherapy. Chest CT demonstrated a 3x2 cm(2) left lower lobe (LLL) mass, with further small nodules in the same lobe. A presumptive diagnosis of lung metastases was made, and the patient underwent surgical resection with left lower lobectomy and mediastinal lymph node dissection. Pathologic examination of the masses in the LLL revealed granulomatous inflammation with cryptococcus infection. The dissected lymph nodes revealed anthracosis. The patient received 6 months of antifungal treatment with fluconazole. His NPC showed no evidence of local recurrence or distant metastases. Recognition that pulmonary cryptococcus infection can mimic metastases is important in reaching the correct diagnosis and therefore determining the correct treatment.
