    Abstract Background: A calcified amorphous tumour (CAT) is a non-neoplastic mass lesion arising within the cardiac chamber. CATs are rare but are a common cause of organ embolism. In the present study, we experienced a case of an intracardiac mass with calcification that, in contrast to a typical CAT, suddenly appeared and rapidly expanded without an inflammatory response based on pathological findings.
    Case summary: A 58-year-old Japanese man undergoing peritoneal haemodialysis had a high-echoic mobile mass (15 × 6 mm), which was not visible on the transthoracic echocardiography (TTE) approximately a month earlier, in the left ventricular outflow tract noted on TTE performed during a close examination for fever. Although multiple blood cultures were negative, ampicillin/sulbactam and ceftriaxone were initially administered because of suspected blood culture-negative endocarditis. The mass rapidly enlarged (22 × 5 mm) over the following days. A CAT was suspected and resected based on imaging findings with calcification; however, the pathological findings did not indicate inflammation and fibrin that are typically found in CATs. Echocardiography performed 12 months after the resection showed no recurrence.
    Discussion: This intracardiac calcified tissue had several similar features to a CAT. However, the initial presentation, enlargement rate, and pathological features of the tissue differed from that of a typical CAT. Although it is unknown whether this mass is a subtype of CAT, when an intracardiac calcified tissue is detected using an imaging test, careful follow-up or early surgical resection should be considered given the possibility of rapid tissue enlargement and embolism caused by the mass.

    Abstract Recent experimental research has observed two kinds of priming effects on quantity implicatures. One is the Strong-Weak contrast, where more quantity implicatures are observed after prime trials forcing interpretations with quantity implicatures ('Strong primes') than after prime trials forcing interpretations without quantity implicatures ('Weak primes'). The other effect is the Alternative-Weak contrast, where prime trials mentioning alternative expressions ('Alternative primes') similarly lead to more quantity implicatures. It has been claimed that both of these effects should be understood in terms of increased salience of alternative expressions used to compute quantity implicatures. We present experimental evidence that speaks against this hypothesis. With the help of novel baseline conditions, which were absent in previous studies on implicature priming, we observe that the results in the priming paradigm commonly used in the literature are inverse preference effects in the sense that robust priming effects are observed towards interpretations that are normally unexpected, and depending on the baseline expectation, each of the three prime types mentioned above may have priming effects. We furthermore investigated different types of alternative priming for so-called ad hoc implicatures and found that for these implicatures, presenting an alternative expression in a simple sentence does not have a priming effect on the implicature of a similarly simple sentence, but presenting it in a more complex conjunctive construction does. Our results also show that conjunctions of similar but irrelevant expressions have a similarly robust priming effect and that conjunctive sentences with two conjuncts do not give rise to priming effects on the interpretation of sentences of the same syntactic complexity, but those with three conjuncts do. To make sense of these observations, we propose that what crucially matters for priming implicatures is incremental change in one's probabilistic expectations about the current conversational context brought about by a process we call context adaptation.

    Abstract Background: Primary plasma cell leukaemia is rarely associated with high-output heart failure, and the underlying mechanism is not well understood. We encountered a rare case of high-output heart failure caused by primary plasma cell leukaemia. Its underlying mechanism was clarified through imaging studies.
    Case summary: A 49-year-old man with no specific medical history was admitted to our hospital because of heart failure that did not improve with diuretic therapy. His condition was diagnosed as high-output heart failure and primary plasma cell leukaemia after admission. Extensive bone involvement in primary plasma cell leukaemia and arteriovenous shunts in the same lesion were suspected after various imaging studies. The first cycle of chemotherapy with bortezomib, adriamycin, and dexamethasone led to remission of primary plasma cell leukaemia and improved heart failure symptoms. The patient received further chemotherapy in addition to autologous peripheral blood stem cell transplantation and maintenance therapy and had no recurrence of pPCL or heart failure for 1 year to date.
    Discussion: Primary plasma cell leukaemia can be associated with high-output heart failure, which is caused by arteriovenous shunting at the lesion site with diffuse bone involvement. Imaging studies may lead to the early diagnosis of aetiology and treatment of patients with high-output heart failure associated with primary plasma cell leukaemia.

    Abstract Microbial rhodopsins are photoreceptive membrane proteins showing various light-dependent biological activities. Styrene-maleic acid (SMA) copolymers spontaneously form nanoscale lipid particles containing membrane proteins and associated lipids without detergent, and can be used to characterize membrane molecules. Here, we provide a protocol to functionally express a thermally stable rhodopsin,

    Abstract Retinal proteins possess vitamin A aldehyde (retinal) as a chromophore within seven transmembrane α-helices. Visible light absorption of them triggers trans-cis photoisomerization of the retinal chromophore and induces structural changes in the protein moiety, resulting in a variety of biological functions such as vision, ion transportation, and photosensing. Environmental genomics revealed that retinal proteins are widely distributed through all three biological kingdoms, eukarya, bacteria, and archaea, indicating the biological significance of their light energy conversion. In addition to their biological aspect, retinal proteins have become a focus of interest in part because of applications for optogenetics. On the basis of our results and other findings, we highlight the recent progress in structural and functional studies on retinal proteins.

    Abstract The capability of focus control has been central to optical technologies that require both high temporal and spatial resolutions. However, existing varifocal lens schemes are commonly limited to the response time on the microsecond timescale and share the fundamental trade-off between the response time and the tuning power. Here, we propose an ultrafast holographic focusing method enabled by translating the speed of a fast 1D beam scanner into the speed of the complex wavefront modulation of a relatively slow 2D spatial light modulator. Using a pair of a digital micromirror device and a resonant scanner, we demonstrate an unprecedented refresh rate of focus control of 31 MHz, which is more than 1,000 times faster than the switching rate of a digital micromirror device. We also show that multiple micrometer-sized focal spots can be independently addressed in a range of over 1 MHz within a large volume of 5 mm × 5 mm × 5.5 mm, validating the superior spatiotemporal characteristics of the proposed technique - high temporal and spatial precision, high tuning power, and random accessibility in a three-dimensional space. The demonstrated scheme offers a new route towards three-dimensional light manipulation in the 100 MHz regime.
